Entropy Constraints for Ground Energy Optimization
Hamza Fawzi, Omar Fawzi, Samuel O. Scalet
We study the use of von Neumann entropy constraints for obtaining lower bounds on the ground energy of quantum many-body systems. Known methods for obtaining certificates on the gr…
Security of discrete-modulated continuous-variable quantum key distribution
Stefan Bäuml, Carlos Pascual-García, Victoria Wright +2
Continuous variable quantum key distribution with discrete modulation has the potential to provide information-theoretic security using widely available optical elements and existi…
Quantum Channel Certification with Incoherent Strategies
Omar Fawzi, Nicolas Flammarion, Aurélien Garivier +1
In the problem of quantum channel certification, we have black box access to a quantum process and would like to decide if this process matches some predefined specification or is…
A lower bound on the overhead of quantum error correction in low dimensions
Nouédyn Baspin, Omar Fawzi, Ala Shayeghi
We show that a quantum architecture with an error correction procedure limited to geometrically local operations incurs an overhead that grows with the system size, even if arbitra…
Lower Bounds on Learning Pauli Channels with Individual Measurements
Omar Fawzi, Aadil Oufkir, Daniel Stilck França
Understanding the noise affecting a quantum device is of fundamental importance for scaling quantum technologies. A particularly important class of noise models is that of Pauli ch…
Asymptotic Equipartition Theorems in von Neumann algebras
Omar Fawzi, Li Gao, Mizanur Rahaman
The Asymptotic Equipartition Property (AEP) in information theory establishes that independent and identically distributed (i.i.d.) states behave in a way that is similar to unifor…
