Latest Quantum information science Stories
A new paradigm in quantum information processing has been demonstrated by physicists at UC Santa Barbara.
Thanks to advances in experimental design, physicists at the National Institute of Standards and Technology (NIST) have achieved a record-low probability of error in quantum information processing with a single quantum bit (qubit)—the first published error rate small enough to meet theoretical requirements for building viable quantum computers.
Quantum communication could be an option for the absolutely secure transfer of data.
Physicists have discovered that the quantum properties of ions can be manipulated using microwaves, instead of lasers.
Dr Xiao-Qi Zhou and colleagues at the University of Bristol's Centre for Quantum Photonics and the University of Queensland, Australia, have shown that controlled operations â€” ones that are implemented on the condition that a "control bit" is in the state 1 â€” can be dramatically simplified compared to the standard approach.
No-one likes a know-it-all but we expect to be able to catch them out: someone who acts like they know everything but doesn't can always be tripped up with a well-chosen question.
Scientists have taken the next major step toward quantum computing, which will use quantum mechanics to revolutionize the way information is processed.
Researchers at the National Institute of Standards and Technology (NIST) have created a tunable superconducting circuit on a chip that can place a single microwave photon (particle of light) in two frequencies, or colors, at the same time.
A Princeton researcher and his international collaborators have used lasers to peek into the complex relationship between a single electron and its environment, a breakthrough that could aid the development of quantum computers.
Physicists working at the University of California, Santa Barbara and the University of Konstanz in Germany have developed a breakthrough in the use of diamond in quantum physics, marking an important step toward quantum computing.
