Energetic cost of Hamiltonian quantum gates [PDF]
Europhysics letters, 2021 Landauer's principle laid the main foundation for the development of modern thermodynamics of information. However, in its original inception the principle relies on semiformal arguments and dissipative dynamics.

Quantum Teleportation of Optical Quantum Gates [PDF]
Physical Review Letters, 2003 We show that a universal set of gates for quantum computation with optics can be quantum teleported through the use of EPR entangled states, homodyne detection, and linear optics and squeezing operations conditioned on measurement outcomes. This scheme may be used for fault-tolerant quantum computation in any optical scheme (qubit or continuous ...

Fast Multiqubit Gates through Simultaneous Two-Qubit Gates
PRX Quantum, 2021 Near-term quantum computers are limited by the decoherence of qubits to only being able to run low-depth quantum circuits with acceptable fidelity. This severely restricts what quantum algorithms can be compiled and implemented on such devices.
