Overview

Experimental study demonstrates an 11-channel integrated quantum memory with random access and high-dimensional storage, suggesting a scalable hardware platform for advanced quantum networks.

Key Points

To develop a scalable, multichannel integrated solid-state quantum memory capable of random-access retrieval and high-dimensional photonic quantum state storage.
Fabricated an 11-channel waveguide array inside a europium-doped yttrium orthosilicate (151Eu3+:Y2SiO5) crystal using direct laser writing.
Patterned on-chip electrode arrays to independently control channel readout timing through Stark-shift-induced atomic interference.
Achieved random-access quantum storage of three time-bin qubits with retrieval fidelity exceeding 99%.
Demonstrated storage of five-dimensional path-encoded quantum states with retrieval fidelity exceeding 96%.
