Selective decoupling and Hamiltonian engineering in dipolar spin networks
Ashok Ajoy, Ulf Bissbort, Dario Poletti +1
We present a protocol to selectively decouple, recouple, and engineer effective couplings in mesoscopic dipolar spin networks. In particular, we develop a versatile protocol that r…
Converting heat into directed transport on a tilted lattice
Colin Teo, Ulf Bissbort, Dario Poletti
We present a self-contained engine, which is made of one or more two-level systems, each of which is coupled to a single bath, as well as to a common load composed of a particle on…
Operator-based derivation of phonon modes and characterization of correlations for trapped ions at zero and finite temperature
Ulf Bissbort, Walter Hofstetter, Dario Poletti
We present a self-contained operator-based approach to derive the spectrum of trapped ions. This approach provides the complete normal form of the low energy quadratic Hamiltonian…
Quantum Interpolation for High Resolution Sensing
A. Ajoy, Y. X. Liu, K. Saha +4
Recent advances in engineering and control of nanoscale quantum sensors have opened new paradigms in precision metrology. Unfortunately, hardware restrictions often limit the senso…
Atomic-scale nuclear spin imaging using quantum-assisted sensors in diamond
Ashok Ajoy, Ulf Bissbort, Mikhail D. Lukin +2
Nuclear spin imaging at the atomic level is essential for the understanding of fundamental biological phenomena and for applications such as drug discovery. The advent of novel nan…
