Scaling silicon quantum photonic technology

An international team of quantum scientists and engineers led by the University of Bristol and involving groups from China, Denmark, Spain, Germany and Poland, have realised an advanced large-scale silicon quantum photonic device that can entangle photons to incredible levels of precision.

While standard quantum hardware entangles particles in two states, the team has found a way to generate and entangle pairs of particles that each has 15 states.

The integrated photonic chip sets a new standard for complexity and precision of quantum photonics, with immediate applications for quantum technologies.
