In December 2019, Amazon Web Services announced a partnership with Caltech to establish the AWS Center for Quantum Computing. Physics 125ab. ", Albert says that the trio of himself, Preskill, and Covey provided the perfect combination of theoretical and experimental expertise to achieve the latest results. Quantum Mechanics. And then we can kick the system back to compensate.". Feedback? Back then, the scientists proposed a loophole that would provide a way around a phenomenon called Heisenberg's uncertainty principle, which was introduced in 1927 by German physicist Werner Heisenberg.
CS/EE/Ma 129 abc.
", Says Preskill, "This is a paper that no one of the three of us could have written on our own. Biomolecular Computation.
"People have been thinking about using molecules to encode information since 2001, but now we are showing how molecules, which are more complex than atoms, could lead to fewer errors in quantum computing.". Blog. MC 305-16, Pasadena, CA 91125. To make the chips a practical option in quantum networks designed to transmit information over long distances, they need to be able to store the data for at least one millisecond.
“Caltech has a history of breakthroughs in experimental and theoretical quantum science and technology and has become a leading incubator in the emerging field of quantum engineering… In a new theoretical study, Caltech physicists have shown how molecules can, in theory, be used to reduce errors in quantum computing. Topics in quantum information. However, if a quantum computer platform uses qubits made of molecules, the researchers say, these types of errors are more likely to be prevented than in other quantum platforms. He and his team have made strides in using optical laser beams, or "tweezers," to control single neutral atoms (neutral atoms are another promising platform for quantum-information systems). The uncertainty principle is a challenge for quantum computers because it implies that the quantum states of the qubits cannot be known well enough to determine whether or not errors have occurred. The breakthrough is the latest step towards quantum computers and networks, which would allow information to be processed and transmitted faster and with smaller devices. The laws of quantum mechanics govern the behavior of infinitesimal particles such as individual photons or electrons.

This error-correcting scheme, known as GKP after its discoverers, has recently been implemented in superconducting circuit devices. And then we can kick the system back to compensate.". "There is a joke where Heisenberg gets pulled over by a police officer who says he knows Heisenberg's speed was 90 miles per hour, and Heisenberg replies, 'Now I have no idea where I am,'" says Albert. Caltech has benefited greatly from its long tradition of multidisciplinary collaborations between different researchers with various complementary experience. "If we can figure out how to utilize molecules in quantum computing, we can robustly encode information and improve the efficiency in which qubits are packed.
