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…
On-Demand Millisecond Storage of Spectro-Temporal Multimode Telecom Photons
Anuj Sethia, Nasser Gohari Kamel, Daniel Oblak
The realization of scalable quantum networks for distribution of entanglement over long distances hinges on quantum repeaters. To outperform the exponential transmission loss in op…
Hole burning experiments and modeling in erbium-doped silica glass fibers down to millikelvin temperatures: evidence for ultra-long population storage
Mahdi Bornadel, Sara Shafiei Alavijeh, Farhad Rasekh +5
We use spectral hole burning to investigate spin dynamics within the electronic Zeeman sublevels of the ground state of the erbium ions in erbium-doped fibers (EDF). Conducted at u…
Ultra-narrow homogeneous linewidths of erbium-doped silica glass fibers at millikelvin temperatures: magnetic field and temperature dependence
Farhad Rasekh, Nasser Gohari Kamel, Mahdi Bornadel +4
Erbium-doped solids are promising candidates for fiber-based quantum networks due to their emission wavelength, which aligns with the telecom band over which optical fibers exhibit…
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…
