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 ones that are implemented on the condition that a "control bit" is in the state 1 can be dramatically simplified compared to the standard approach. The researchers believe their technique will find applications across quantum information technologies, including precision measurement, simulation of complex systems, and ultimately a quantum computer a powerful type of computer that uses quantum bits (qubits) rather than the conventional bits used in today's computers.
