Latest Quantum circuit Stories
The team implemented the 'phase estimation algorithm' — a central quantum algorithm which achieves an exponential speedup over all classical algorithms.
A new paradigm in quantum information processing has been demonstrated by physicists at UC Santa Barbara.
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.
An important step â€“â€“ one that is essential to the ultimate construction of a quantum computer â€“â€“ was taken for the first time by physicists at UC Santa Barbara.
Scientists at UC Santa Barbara have devised a new type of superconducting circuit that behaves quantum mechanically â€“â€“ but has up to five levels of energy instead of the usual two.
