Regularized Warm-Started Quantum Approximate Optimization and Conditions for Surpassing Classical Solvers on the Max-Cut Problem

Zichang He, Anuj Apte, Brandon Augustino +4

Demonstrating quantum heuristics that outperform strong classical solvers on large-scale optimization remains an open challenge. Here we introduce Regularized Warm-Started QAOA (RW…

Digital signatures with classical shadows on near-term quantum computers

Pradeep Niroula, Minzhao Liu, Sivaprasad Omanakuttan +15

Quantum mechanics provides cryptographic primitives whose security is grounded in hardness assumptions independent of those underlying classical cryptography. However, existing pro…

Holstein Primakoff spin codes for local and collective noise

Sivaprasad Omanakuttan, Tyler Thurtell, Andrew K. Forbes +2

Quantum error correction is essential for fault-tolerant quantum computation, yet most existing codes rely on local control and stabilizer measurements that are difficult to implem…

Realization of a Quantum Streaming Algorithm on Long-lived Trapped-ion Qubits

Pradeep Niroula, Shouvanik Chakrabarti, Steven Kordonowy +30

Large classical datasets are often processed in the streaming model, with data arriving one item at a time. In this model, quantum algorithms have been shown to offer an unconditio…
