Washington, Mar 2 (ANI): Researchers at University of Bristol have demonstrated the quantum operation of new components that will enable compact circuits for future photonic quantum computers.
Dr Terry Rudolph at Imperial College, London, shows a new class of integrated divides that promise further reduction in the number of components that will be used for building future quantum circuits.
"While building a complex quantum network requires a large number of basic components, MMIs (multimode interference) can often enable the implementation with much fewer resources," said Alberto Peruzzo.
The researchers have demonstrated that MMIs can perform quantum interference at the high fidelity required.
This will enable scientists to implement more compact photonics circuits for quantum computing. MMIs can generate large entangled states, at the heart of the exponential speedup promised by quantum computing.
"Applications will range from new circuits for quantum computation to ultra precise measurement and secure quantum communication," said Professor Jeremy O'Brien, director of the Centre for Quantum Photonics.
The team's next plan is to build new sophisticated circuits for quantum computation and quantum metrology using MMI devices. (ANI)
