Imperial engineers build a reconfigurable photonic quantum chip
Imperial College London engineers have fabricated a reconfigurable photonic quantum chip that can dynamically change its optical circuits. The chip uses integrated Mach-Zehnder interferometers and phase shifters to implement arbitrary unitary transformations without hardware modifications.
