Dense Coding with Linear Optics without Bell State Measurements
2015 · arXiv (Cornell University)
Entanglement can effectively increase communication channel capacity as evidenced by dense coding that predicts a capacity gain of 1 bit when compared to entanglement-free protocols. However, dense coding relies on Bell states and when implemented …

Digital-Analog Quantum Simulations Using the Cross-Resonance Effect
2021 · PRX Quantum
Digital-analog quantum computation aims to reduce the currently infeasible resource requirements needed for near-term quantum information processing by replacing sequences of one-and two-qubit gates with a unitary transformation generated by the systems' underlying Hamiltonian. Inspired …

Quantifying the Impact of Precision Errors on Quantum Approximate Optimization Algorithms
2021 · arXiv (Cornell University)
The quantum approximate optimization algorithm (QAOA) is a hybrid quantum-classical algorithm that seeks to achieve approximate solutions to optimization problems by iteratively alternating between intervals of controlled quantum evolution. Here, we examine the effect of …
