Dissipative superradiant spin amplifier for enhanced quantum sensing
Martin Koppenhöfer, Peter Groszkowski, Hoi-Kwan Lau +1
Quantum metrology protocols exploiting ensembles of two-level systems and Ramsey-style measurements are ubiquitous. However, in many cases excess readout noise severely degrade…
Coherent Spin Preparation of Indium Donor Qubits in Single ZnO Nanowires
Maria L. K. Viitaniemi, Christian Zimmermann, Vasileios Niaouris +6
Shallow donors in ZnO are promising candidates for photon-mediated quantum technologies. Utilizing the indium donor, we show that favorable donor-bound exciton optical and electron…
Robotized polarization characterization platform for free-space quantum communication optics
Youn Seok Lee, Kimia Mohammadi, Lindsay Babcock +3
We develop a polarization characterization platform for optical devices in free-space quantum communications. We demonstrate an imaging polarimeter, which analyzes both incident po…
The dihedral hidden subgroup problem
Imin Chen, David Sun
We give an exposition of the hidden subgroup problem for dihedral groups from the point of view of the standard hidden subgroup quantum algorithm for finite groups. In particular,…
Reservoir-engineered spin squeezing: macroscopic even-odd effects and hybrid-systems implementations
Peter Groszkowski, Martin Koppenhöfer, Hoi-Kwan Lau +1
We revisit the dissipative approach to producing and stabilizing spin-squeezed states of an ensemble of two-level systems, providing a detailed analysis of two surprising yet g…
Quantum annealing simulation of out-of-equilibrium magnetization in a spin-chain compound
Andrew D. King, Cristian D. Batista, Jack Raymond +5
Geometrically frustrated spin-chain compounds such as Ca3Co2O6 exhibit extremely slow relaxation under a changing magnetic field. Consequently, both low-temperature laboratory expe…
Discrete phase space and continuous time relativistic quantum mechanics II: Peano circles, hyper-tori phase cells, and fibre bundles
Anadijiban Das, Rupak Chatterjee
The discrete phase space and continuous time representation of relativistic quantum mechanics is further investigated here as a continuation of paper I [1]. The main mathematical c…
