Quantum trajectories, interference, and state localisation in dephasing assisted quantum transport

Kiran E. Khosla, Ardalan Armin, M. S. Kim

Dephased quantum transport of excitations occurs when energetic fluctuations in a system are sufficient to suppress the built-up of coherent amplitudes. While this has been extensi…

Torque-free manipulation of nanoparticle rotations via embedded spins

Yue Ma, M. S. Kim, Benjamin A. Stickler

Spin angular momentum and mechanical rotation both contribute to the total angular momentum of rigid bodies, leading to spin-rotational coupling via the Einstein-de Haas and Barnet…

Optimal training of variational quantum algorithms without barren plateaus

Tobias Haug, M. S. Kim

Variational quantum algorithms (VQAs) promise efficient use of near-term quantum computers. However, training VQAs often requires an extensive amount of time and suffers from the b…

Quantum teleportation is a reversal of quantum measurement

Seung-Woo Lee, Dong-Gil Im, Yoon-Ho Kim +2

We introduce a generalized concept of quantum teleportation in the framework of quantum measurement and reversing operation. Our framework makes it possible to find an optimal prot…

Quantum rotations of nanoparticles

Benjamin A. Stickler, Klaus Hornberger, M. S. Kim

Rotations of microscale rigid bodies exhibit pronounced quantum phenomena that do not exist for their center-of-mass motion. By levitating nanoparticles in ultra-high vacuum, resea…

Variational quantum algorithm with information sharing

Chris N. Self, Kiran E. Khosla, Alistair W. R. Smith +5

We introduce an optimisation method for variational quantum algorithms and experimentally demonstrate a 100-fold improvement in efficiency compared to naive implementations. The ef…
