Programmable Heisenberg interactions between Floquet qubits

2022 · arXiv (Cornell University)

The fundamental trade-off between robustness and tunability is a central challenge in the pursuit of quantum simulation and fault-tolerant quantum computation. In particular, many emerging quantum architectures are designed to achieve high coherence at the …

Entanglement swapping via lossy channels using photon-number-encoded states

2024 · arXiv (Cornell University)

Entanglement shared between distant parties is a key resource in quantum networks. However, photon losses in quantum channels significantly reduce the success probability of entanglement sharing, which scales quadratically with the channel transmission. Quantum repeaters …
