Local transformations of bipartite entanglement are rigid
John Bostanci, Tony Metger, Henry Yuen
Uhlmann's theorem is a fundamental result in quantum information theory that quantifies the optimal overlap between two bipartite pure states after applying local unitary operation…
A General Quantum Duality for Representations of Groups with Applications to Quantum Money, Lightning, and Fire
John Bostanci, Barak Nehoran, Mark Zhandry
Aaronson, Atia, and Susskind (2020) established that efficiently mapping between quantum states and is computationally equivalent to distinguishing their su…
Efficient Quantum Pseudorandomness from Hamiltonian Phase States
John Bostanci, Jonas Haferkamp, Dominik Hangleiter +1
Quantum pseudorandomness has found applications in many areas of quantum information, ranging from entanglement theory, to models of scrambling phenomena in chaotic quantum systems…
Oracle Separation Between Quantum Commitments and Quantum One-wayness
John Bostanci, Boyang Chen, Barak Nehoran
We show that there exists an oracle relative to which quantum commitments exist but no (efficiently verifiable) one-way state generators exist. Both have been widely considered can…
