(Phys.org) —A team of researchers working at the University of Oxford has found that quantum bits (qubits) based on trapped calcium ions can be both manipulated and fashioned to store qubits with higher fidelity than any ...
(Phys.org) —A team of researchers working in South Africa has reported that they've successfully run Simon's algorithm on a quantum computer for the first time. In their paper published in Physical Review Letters, the team ...
Two research teams working in the same laboratories at UNSW Australia have found distinct solutions to a critical challenge that has held back the realisation of super powerful quantum computers.
