Project description
Erbium-ion quantum register for next-generation computing and communications
Erbium ions embedded in crystals are promising candidates for quantum information processing owing to their unique properties, such as optical transition at telecom bands and the formation of large magnetic dipoles. The development of a hybrid quantum register combining fast control, high-fidelity readout and long memory time promises significant capacities in quantum computing and communications. Unlike previous spin-based quantum registers that rely on system-specific photoluminescence, the EQRSMPD project aims to operate the erbium ion quantum register with a single microwave photon detector. This could enable an interface between quantum registers and microwave photons, paving the way for advanced quantum applications of erbium ions, long-distance spin-spin entanglement and hybrid quantum information platforms. EQRSMPD is funded by the Marie Skłodowska-Curie Actions programme.
Objective
Erbium ion embedded in crystal is a promising candidate for quantum information processing for its unique properties, such as optical transition at telecom band and large magnetic dipole. Erbium nuclear spin has long coherence time and is ideal for working as quantum memories. A hybrid quantum register formed by erbium electron spin, intrinsic nuclear spin and nearby nuclear spins in the host crystal combining fast control, high-fidelity readout and long memory time will have huge capacities in quantum applications, such as quantum computing and quantum communication. Previous spin-based quantum registers rely on the spin-dependent photoluminescence, which is system specific. In this project, we propose to realize erbium ion quantum register operated with a single microwave photon detector which is based on a superconducting transom qubit and works in principle for any spin system. This project will enable interface between quantum register and microwave photons, and pave the way for more sophisticated quantum applications of erbium ions, long-distance spin-spin entanglement, and hybrid quantum information platforms.
