Instantiating Microcrypt: Obstacles and opportunities via tailored state certification
Jose Carrasco, Jens Eisert, Soumik Ghosh +3
Recent work has introduced the Hamiltonian phase state (HPS) assumptions, which postulate that Hamiltonian phase states can be used to instantiate pseudorandom and one-way state ge…
Sampling hard circuits with verifiably high fidelity
Simon Martiel, Jay-U Chung, Alireza Seif +9
Sampling-based proposals are prominent candidates for demonstrating quantum computations beyond the reach of classical supercomputers. However, it has been difficult to combine the…
Sample-efficient benchmarking of shallow all-to-all random quantum circuits
Gregory Bentsen, Bill Fefferman, Soumik Ghosh +2
Random circuit sampling (RCS) remains one of the most competitive frameworks for demonstrating quantum advantage in near-term noisy intermediate-scale quantum (NISQ) hardware. Unfo…
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…
Unconditional Pseudorandomness against Shallow Quantum Circuits
Soumik Ghosh, Sathyawageeswar Subramanian, Wei Zhan
Quantum computational pseudorandomness has emerged as a fundamental notion that spans connections to complexity theory, cryptography and fundamental physics. However, all known con…
