Coherent microwave-to-optical transduction with Yb:YSO spins strongly coupled to a 3D resonator
Ujjwal Gautam, Nasser Gohari Kamel, Sourabh Kumar +1
Microwave-to-optical quantum transducers are essential for entangling remote superconducting qubits. Among the available transduction platforms, ensembles of Er and Yb$^{3+}…
Memory-assisted multimode microwave-to-optical transduction
Ujjwal Gautam, Nasser Gohari Kamel, Sourabh Kumar +1
Microwave-to-optical quantum transducers will enable coherent interconnection between distant superconducting quantum devices. Ongoing explorations with several platforms have show…
Erbium-Doped Fibre Quantum Memory for Chip-Integrated Quantum-Dot Single Photons at 980 nm
Nasser Gohari Kamel, Arsalan Mansourzadeh, Ujjwal Gautam +8
The realization of long-distance quantum communication and the envisioned quantum internet relies on coherent hybrid light-matter interfaces connecting quantum light emitters with…
Multimode and Random-Access Optical Quantum Memory via Adiabatic Phase Imprinting
Nasser Gohari Kamel, Sourabh Kumar, Ujjwal Gautam +3
A photonic quantum memory capable of simultaneously storing multiple qubits and subsequently recalling any randomly selected subset of the qubits, is essential for large-scale quan…
