Classical Communication Helps Single-Shot Quantum Compression
Omri Farber, Gilad Gour
Free classical communication can yield an unbounded single-shot saving in quantum compression, even though it leaves the asymptotic rate of an i.i.d. source unchanged. At every fix…
Failure of the Asymptotic Equipartition Property for Quantum Channels
Gilad Gour
We establish two results on the asymptotic equipartition property (AEP) for quantum channels. First, the AEP formulated using smoothing over completely positive trace-preserving ma…
Quantum Noncommutativity Uniquely Determines Relative Entropy
Gilad Gour
Quantum relative entropy is a core concept in physics, governing the limits of communication, thermodynamic irreversibility and quantum resource conversion. However, the requiremen…
Optimal Trace Inequalities for Single-Shot Quantum Information
Gilad Gour
Single-shot quantum information theory is governed not only by entropy exponents, but also by the finite-resource constants that multiply them. These constants directly affect the…
Optimal Universal Bounds for Quantum Divergences
Gilad Gour
We identify a universal structural principle underlying the smoothing of classical divergences: the optimizer of the smoothing problem is a clipped probability vector, independentl…
Instability as a Quantum Resource
Goni Yoeli, Gilad Gour
We consolidate coherence, athermality, and nonuniformity as sub-resources within an underlying quantum resource theory: instability. We formulate instability axiomatically as the t…
