Coherent Control of Quantum-Dot Spins with Cyclic Optical Transitions
Zhe Xian Koong, Urs Haeusler, Jan M. Kaspari +14
Solid-state spins are promising as interfaces from stationary qubits to single photons for quantum communication technologies. Semiconductor quantum dots have excellent optical coh…
Decoy-state quantum key distribution over 227 km with a frequency-converted telecom single-photon source
Frederik Brooke Barnes, Roberto G. Pousa, Christopher L. Morrison +7
We implement a decoy-state quantum key distribution scheme using a telecom C-band single-emitter source. The decoy states are created by varying the optical excitation of the quant…
Experimental distributed quantum sensing in a noisy environment
James Bate, Arne Hamann, Marco Canteri +5
The precision advantages offered by harnessing the quantum states of sensors can be readily compromised by noise. However, when the noise has a different spatial function than the…
Optical and magnetic response by design in GaAs quantum dots
Christian Schimpf, Ailton J. Garcia, Zhe X. Koong +24
Quantum networking technologies use spin qubits and their interface to single photons as core components of a network node. This necessitates the ability to co-design the magnetic-…
A photon-interfaced ten qubit quantum network node
M. Canteri, Z. X. Koong, J. Bate +3
We entangle each individual matter-qubit in a register of ten to a separate travelling photon. The qubits are encoded in a string of cotrapped atomic ions. By switching the trap co…
