Decoherence enhances performance of quantum walks applied to graph isomorphism testing
M. Bruderer, M. B. Plenio
Computational advantages gained by quantum algorithms rely largely on the coherence of quantum devices and are generally compromised by decoherence. As an exception, we present a q…
Sensing of single nuclear spins in random thermal motion with proximate nitrogen-vacancy centers
M. Bruderer, P. Fernández-Acebal, R. Aurich +1
Nitrogen-vacancy (NV) centers in diamond have emerged as valuable tools for sensing and polarizing spins. Motivated by potential applications in chemistry, biology, and medicine, w…
Inverse counting statistics for stochastic and open quantum systems: the characteristic polynomial approach
M. Bruderer, L. D. Contreras-Pulido, M. Thaller +3
We consider stochastic and open quantum systems with a finite number of states, where a stochastic transition between two specific states is monitored by a detector. The long-time…
Controlling and measuring quantum transport of heat in trapped-ion crystals
A. Bermudez, M. Bruderer, M. B. Plenio
Measuring heat flow through nanoscale systems poses formidable practical difficulties as there is no `ampere meter' for heat. We propose to overcome this problem by realizing heat…
Entanglement generation in a system of two atomic quantum dots coupled to a pool of interacting bosons
Anna Posazhennikova, Reinhard Birmuske, Martin Bruderer +1
We discuss entanglement generation in a closed system of one or two atomic quantum dots (qubits) coupled via Raman transitions to a pool of cold interacting bosons. The system exhi…
Exploiting boundary states of imperfect spin chains for high-fidelity state transfer
M. Bruderer, K. Franke, S. Ragg +2
We study transfer of a quantum state through XX spin chains with static imperfections. We combine the two standard approaches for state transfer based on (i) modulated couplings be…
