Quantum to Classical Crossover in Mechanical Systems Leiden 
Lorentz Center Workshop on the Quantum to Classical Crossover in Mechanical Systems 

In recent years there have been rapid developments in controlling micro- and nanometer-sized mechanical systems—to the point where quantum physics has become essential for understanding the dynamics of these systems. Quantized oscillations of mechanical resonators are now being discussed, and these have potential applications in the field of quantum information science.

New, fundamental tests of quantum mechanics—such as superpositions of states and entanglement between systems—are now within reach for macroscopic objects. These experimental possibilities provide new input to the discussion of how the classical world emerges from underlying quantum physics. A related question, whether quantum physics is needed to understand properties beyond those of the chemical reactions and molecular compositions of biological systems, will also be addressed. This Lorentz Center Workshop will bring together leading experimentalists and theorists in this field of research.

Workshop participants include Dirk Bouwmeester, Yaroslav Blanter, Herre van der Zant, Eva Weig, Markus Aspelmeyer, Hans Briegel, Andrew Cleland, Rosario Fazio, Philip Stamp, Wojciech Zurek, and many more.

Extending coherence times in superconducting qubits Schoelkopf Lab | via Leo DiCarlo — In arXiv 1105.4652, Schoelkopf et al  report novel implementation of a superconducting transmon qubit strongly coupled to a 5-cm, three-dimensional superconducting cavity, attaining reproducible extension in coherence times of both qubit (T₁ and T₂ > 10 μs) and cavity (T_cav ∼ 50 μs) by more than an order of magnitude compared to the current state-of-the-art superconducting qubits. "This enables the study of the stability and quality of Josephson junctions at precisions exceeding one part per million. Surprisingly, we see no evidence for 1/ f critical current noise. At elevated temperatures, we observe dissipation due to a small density (< 1 − 10 ppm) of thermally excited quasiparticles. These results suggest that the overall quality of Josephson junctions will allow for error rates of 10⁻⁴, approaching the error correction threshold to meet the DiVincenzo criteria for universal quantum computation. 





Time domain measurement of qubit coherence (a) Relaxation from |1⟩ of qubit J1. T1 is 60 μs for this measurement. (b) Ramsey fringes measured on resonance with (blue squares) and without (red squares) echo sequence. The pulse width for the π and π/2 pulses used in the experiments is 20 ns. An additional phase is added to the rotation axis of the second π/2 pulse for each delay to give the oscillatory feature to the Ramsey fringes.

The Quantum Computer is Growing Up: Robust error correction in a quantum processor Rainer Blatt | Innsbruck | Science | KurzweilAI 

A more efficient algorithm for error correction in quantum computers has been demonstrated experimentally by physicists at the Institute for Experimental Physics of the University of Innsbruck and the Institute for Quantum Optics and Quantum Information of the Austrian Academy of Sciences (IQOQI).

The physicists demonstrated the mechanism by storing three calcium ions in an ion trap. All three particles were used as qubits: one ion represented the system qubit while the other two ions represented auxiliary qubits. The system qubit was then entangled with the auxiliary qubits to transfer the quantum information to all three particles.

The physicists applied a quantum algorithm to determine whether an error occurred and, if there was an error, correct it. After making the correction, the auxiliary qubits were reset using a laser beam to enable repetitive error correction.

“For a quantum computer to become reality, we need a quantum processor with many quantum bits. Moreover, we need quantum operations that work nearly error-free; the third crucial element is an efficient error correction.”- Philipp Schindler

A team of physicists at the University of Innsbruck, led by Philipp Schindler and Rainer Blatt, has demonstrated a crucial element for quantum computers: repetitive error correction. This allows scientists to correct errors occurring in a quantum computer efficiently. The researchers recently published these findings in Science.

I've recently been selected to train as a scientist-astronaut candidate for commercial suborbital and developing orbital flights with a newly-formed, nonprofit endeavor that counts NASA/ESA astronauts, astronaut trainers and instructors among its astronaut corps and its board of advisors. I'm honored to be selected for the program, and tremendously excited about the opportunity. This is just the start of a long and challenging journey!


The nascent field of commercial spaceflight—and the unique conditions afforded by space and microgravity environments—offer exciting new opportunities to conduct novel experiments in quantum entanglement, fundamental tests of spacetime, and large-scale quantum coherence. In pursuit of these goals, we have the opportunity to inspire our next generation of scientists, researchers and engineers.

Anton Zeilinger: Quantum Entanglement in Space

Quantum Entanglement Allows "Teleportation in Time" MIT Technology Review "Conventional entanglement links particles across space. Now physicists say a similar effect links particles through time. Entanglement is so deeply enmeshed in the universe that a measurement in the past has an automatic, time-symmetric, influence on the future—and vice versa." –MIT Technology Review

Science—Top Breakthrough of the Year Science, UCSB Science Magazine has compiled the top breakthroughs of the year, awarding the most significant scientific advance of 2010 to Andrew Cleland and John Martinis (UCSB). "This year’s Breakthrough of the Year represents the first time that scientists have demonstrated quantum effects in the motion of a human-made object," said Adrian Cho, a news writer for Science. "On a conceptual level it extends quantum mechanics into a whole new realm. On a practical level, it opens up a variety of possibilities ranging from new experiments that meld quantum control over light, electrical currents and motion to—perhaps someday—tests of the bounds of quantum mechanics and our sense of reality. This last grand goal might be achieved by trying to put a macroscopic object in a state in which it’s literally in two slightly different places at the same time."

TEDxCaltech | Feynman's Vision: The Next 50 Years Caltech In recognition of the 50 year anniversaries of Richard Feynman's visionary talk "There's Plenty of Room at the Bottom" and the inauguration of his revolutionary "Feynman Lectures on Physics," the Institute will host TEDxCaltech on January 14, 2011. TEDxCaltech will be a dynamic celebration of Feynman's spirit, curiosity, and scientific vision, and will take ideas worth sharing from Caltech out into the world by celebrating Nobel Laureate, visionary, and “curious character” Richard Feynman, with the theme “Feynman’s Vision: The Next 50 Years.” Speakers include Scott Aaronson, Immanuel Bloch, Sean Carroll, John Preskill, Lenny Susskind, David Awschalom, Kip Thorne, Charlie Marcus, Don Eigler, Michael Roukes, Craig Venter, and many more.

Future holds key to quantum physics—Obama awards National Medal of Science to Aharonov National Medal of Science USAToday | The future is affecting the past—all the time, on the quantum level—allowing physicists to effectively select the future they want their particles to have, within limits, and amplifying the results for a desired outcome. "I really believe we are close to a second revolution in physics as big as the one a century ago," Aharonov says. "I feel we are only beginning to free existing quantum theory and to do so, we must think of time in another way."

I'm recently back from a fellowship in "Quantum Mechanics in Higher Dimensional Hilbert Spaces" at Austrian International Akademie, Traunkirchen, with Anton Zeilinger, Marcus Aspelmeyer, and Caslav Brukner. Photos are now online via the link below.

Quantum computers may be much easier to build than previously thought Physical Review Letters physorg, arXiv "Quantum computers should be much easier to build than previously thought, because they can still work with a large number of faulty or even missing components, according to a study published today in Physical Review Letters. This surprising discovery brings scientists one step closer to designing and building real-life quantum computing system—devices that could have enormous potential across a wide range of fields, from drug design, electronics, and even code-breaking."

Moving Towards Quantum Computing New York Times "Three major technologies have the potential to move from demonstration computers to practical, highly powerful machines. 'We’re at the stage of trying to develop these qubits in a way that would be like the integrated circuit that would allow you to make many of them at once,' said Rob Schoelkopf, a physicist who is leader of the Yale group. In the next few years you’ll see operations on more qubits, but only a handful. The good news is that while the number of qubits is increasing only slowly, the precision with which the researchers are able to control quantum interactions has increased a thousandfold."

Seth Lloyd—Quantum effects in Biological Systems MIT cbc.ca "Lloyd's biological research, funded by the US Defense Advanced Research Projects Agency, looks at how living things use quantum computation [...] Bird navigation, plant photosynthesis and the sense of smell all represent ways living things appear to exploit the oddities of quantum physics."

"We believe it is timely to set out on a distinct quantum biology agenda. The burgeoning fields of nanotechnology, biotechnology, quantum technology, and quantum information processing are now strongly converging. As quantum engineering and nanotechnology meet, increasing use will be made of biological structures, or hybrids of biological and fabricated systems, for producing novel devices for information storage and processing, to create [novel sensors], and for other tasks. If experiments can shed further light on our understanding of decoherence in biomolecules, at scales where equilibrium thermodynamics no longer applies, this may provide the required foundation for greatly accelerating our progress in manmade quantum computers."
