Randomness can be certified in energy-constrained semi-device-independent scenarios
Shashank Kumar Ranu, Lewis Wooltorton, Alastair A. Abbott +1
The prepare-and-measure framework based on energy constraints offers a practical middle ground between fully device-dependent and device-independent quantum cryptography. The only…
Pauli Encodings & Unclonable Encryption
Pierre Botteron, Sébastien Designolle, Omar Fawzi
The unclonable bit question asks whether quantum encryption can prevent an adversary from producing two systems that both reveal the plaintext once the key is disclosed. We introdu…
On approximate quantum error correction for symmetric noise
Gereon Koßmann, Julius A. Zeiss, Omar Fawzi +1
We revisit the extendability-based semi-definite programming hierarchy introduced by Berta et al. [Mathematical Programming, 1 - 49 (2021)], which provides converging outer bounds…
Sampling (noisy) quantum circuits through randomized rounding
Victor Martinez, Omar Fawzi, Daniel Stilck França
The present era of quantum processors with hundreds to thousands of noisy qubits has sparked interest in understanding the computational power of these devices and how to leverage…
Efficient simulation of parametrized quantum circuits under non-unital noise through Pauli backpropagation
Victor Martinez, Armando Angrisani, Ekaterina Pankovets +2
As quantum devices continue to grow in size but remain affected by noise, it is crucial to determine when and how they can outperform classical computers on practical tasks. A cent…
Optimality of meta-converse for channel simulation
Aadil Oufkir, Omar Fawzi, Mario Berta
We study the effect of shared non-signaling correlations for the problem of simulating a channel using noiseless communication in the one-shot setting. For classical channels, we s…
