A device that can be reprogrammed to perform any quantum function and bring quantum information much closer is being developed at the University of Bristol . The new generation silicon chip can control two qubits of information simultaneously . “One of the experiments is to implement a special class of quantum walk, which allows simultaneous traversing of all possible paths in arbitrarily complex network structures.” Currently , operations needing one bit of information ( a qubit ) can be performed precisely but adding a second qubit creates multiple problems . A team at Bristol University ’s Quantum Engineering Technology Centre has created a quantum processor chip with more than 200 photonic components using metal - oxide - semiconductors which has performed 98 two - qubit operations at 93 % efficiency .
