Memory dimension detection in open quantum dynamics via pseudo-control
Chang Liu, Alexander Yosifov, Ximing Wang +2
Characterising open quantum dynamics requires identifying the environmental degrees of freedom that shape the system's evolution. The memory dimension, defined as the size of the s…
Quantum-classical crossover in fault-tolerant quantum dynamics simulation
Jinzhao Sun, Bozhen Zhou, Jue Xu +28
While quantum computers promise to solve classically intractable problems, identifying the point at which fault-tolerant quantum computation outperforms the best classical algorith…
Entanglement-facilitated macroscopic cluster formation in quantum many-body dynamics
Xiao Wang, Alexander Yosifov, Aditya Iyer +1
Metastable quantum many-body dynamics could facilitate the organisation of microscopic degrees of freedom into macroscopic structures. However, the conditions under which this occu…
Hysteretic squashed entanglement in many-body quantum systems
Siddhartha Das, Alexander Yosifov, Jinzhao Sun
Entanglement in many-body quantum systems is distributed across spatial regions, where its structure often dictates the information-processing capabilities of the state. Yet, chara…
Direct probing of the simulation complexity of open quantum many-body dynamics
Lucia Vilchez-Estevez, Alexander Yosifov, Jinzhao Sun
Simulating open quantum systems is key to understanding non-equilibrium processes, as persistent influence from the environment induces dissipation and can give rise to steady-stat…
On the emergence of quantum memory in non-Markovian dynamics
Alexander Yosifov, Aditya Iyer, Vlatko Vedral +1
The emergence of memory is a hallmark feature of non-Markovian dynamics. However, the type of memory -- classical or quantum -- required to realize certain dynamics remains unknown…
Quantum Homogenization as a Quantum Steady State Protocol on NISQ Hardware
Alexander Yosifov, Aditya Iyer, Daniel Ebler +1
Quantum homogenization is a reservoir-based quantum state approximation protocol, which has been successfully implemented in state transformation on quantum hardware. In this work…
Dissipation-induced Quantum Homogenization for Temporal Information Processing
Alexander Yosifov, Aditya Iyer, Vlatko Vedral
Quantum reservoirs have great potential as they utilize the complex real-time dissipative dynamics of quantum systems for information processing and target time-series generation w…
Efficient Digital Quadratic Unconstrained Binary Optimization Solvers for SAT Problems
Robert Simon Fong, Yanming Song, Alexander Yosifov
Boolean satisfiability (SAT) is a propositional logic problem of determining whether an assignment of variables satisfies a Boolean formula. Many combinatorial optimization problem…
A New Look at the -formulation of the Strong Cosmic Censorship Conjecture
Aditya Iyer, Alexander Y. Yosifov, Vlatko Vedral
We examine the -formulation of the strong cosmic censorship conjecture (SCC) from a quantum complexity-theoretic perspective and argue that for generic black hole parameters…
Holographic Interpretation of Relative State Complexity
Alexander Yosifov, Aditya Iyer, Lachezar Filipov
We investigate a large- CFT in a high-energy pure state coupled to a small auxiliary system of weakly-interacting degrees of freedom, and argue the relative state complexity…
Quantum Complexity and Chaos in Young Black Holes
Alexander Y. Yosifov, Lachezar G. Filipov
We argue the problem of calculating retention time scales in young black holes is a problem of relative state complexity. In particular, we suggest that Alice's ability to estimate…
Nonlocal black hole evaporation and quantum metric fluctuations via inhomogeneous vacuum density
Alexander Y. Yosifov, Lachezar G. Filipov
Inhomogeneity of the actual value of the vacuum energy density is considered in a black hole background. We examine the back-reaction of a Schwarzschild black hole to the highly in…
Entropic Entanglement: Information Prison Break
Alexander Y. Yosifov, Lachezar G. Filipov
We argue certain nonviolent local quantum field theory (LQFT) modification considered at the global horizon () of a static spherically-symmetric black hole can lead to adiaba…
