Continuous Optimization for Satisfiability Modulo Theories on Linear Real Arithmetic
Yunuo Cen, Daniel Ebler, Xuanyao Fong
Efficient solutions for satisfiability modulo theories (SMT) are integral in industrial applications such as hardware verification and design automation. Existing approaches are pr…
Optimality and annealing path planning of dynamical analog solvers
Shu Zhou, K. Y. Michael Wong, Juntao Wang +3
Recently proposed analog solvers based on dynamical systems, such as Ising machines, are promising platforms for large-scale combinatorial optimization. Yet, given the heuristic na…
Phase analysis of Ising machines and their implications on optimization
Shu Zhou, K. Y. Michael Wong, Juntao Wang +3
Ising machines, which are dynamical systems designed to operate in a parallel and iterative manner, have emerged as a new paradigm for solving combinatorial optimization problems.…
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…
Experimental Validation of Enhanced Information Capacity by Quantum Switch in Accordance with Thermodynamic Laws
Cheng Xi, Xiangjing Liu, Hongfeng Liu +6
We experimentally probe the interplay of the quantum switch with the laws of thermodynamics. The quantum switch places two channels in a superposition of orders and may be applied…
Bound on annealing performance from stochastic thermodynamics, with application to simulated annealing
Yutong Luo, Yi-Zheng Zhen, Xiangjing Liu +2
Annealing is the process of gradually lowering the temperature of a system to guide it towards its lowest energy states. In an accompanying paper [Luo et al. Phys. Rev. E 108, L052…
General limit to thermodynamic annealing performance
Yutong Luo, Yi-Zheng Zhen, Xiangjing Liu +2
Annealing has proven highly successful in finding minima in a cost landscape. Yet, depending on the landscape, systems often converge towards local minima rather than global ones.…
Optimal universal quantum circuits for unitary complex conjugation
Daniel Ebler, Michał Horodecki, Marcin Marciniak +3
Let be a unitary operator representing an arbitrary -dimensional unitary quantum operation. This work presents optimal quantum circuits for transforming a number of ca…
Thermodynamics of quantum switch information capacity activation
Xiangjing Liu, Daniel Ebler, Oscar Dahlsten
We address a new setting where the second law is under question: thermalizations in a quantum superposition of causal orders, enacted by the so-called quantum switch. This superpos…
Deterministic transformations between unitary operations: Exponential advantage with adaptive quantum circuits and the power of indefinite causality
Marco Túlio Quintino, Daniel Ebler
This work analyses the performance of quantum circuits and general processes to transform uses of an arbitrary unitary operation into another unitary operation . When…
Experimental Quantum Communication Enhancement by Superposing Trajectories
Giulia Rubino, Lee A. Rozema, Daniel Ebler +8
In quantum communication networks, wires represent well-defined trajectories along which quantum systems are transmitted. In spite of this, trajectories can be used as a quantum co…
Resource theories of communication
Hlér Kristjánsson, Giulio Chiribella, Sina Salek +2
A series of recent works has shown that placing communication channels in a coherent superposition of alternative configurations can boost their ability to transmit information. In…
Quantum advantage in training binary neural networks
Yidong Liao, Daniel Ebler, Feiyang Liu +1
The performance of a neural network for a given task is largely determined by the initial calibration of the network parameters. Yet, it has been shown that the calibration, also r…
Quantum communication in a superposition of causal orders
Sina Salek, Daniel Ebler, Giulio Chiribella
Quantum mechanics allows for situations where the relative order between two processes is entangled with a quantum degree of freedom. Here we show that such entanglement can enhanc…
Quantum speedup in the identification of cause-effect relations
Giulio Chiribella, Daniel Ebler
The ability to identify cause-effect relations is an essential component of the scientific method. The identification of causal relations is generally accomplished through statisti…
Enhanced communication with the assistance of indefinite causal order
Daniel Ebler, Sina Salek, Giulio Chiribella
In quantum Shannon theory, the way information is encoded and decoded takes advantage of the laws of quantum mechanics, while the way communication channels are interlinked is assu…

Giulio Chiribella, Daniel Ebler
We develop a semidefinite programming method for the optimization of quantum networks, including both causal networks and networks with indefinite causal structure. Our method appl…

Felix Tennie, Daniel Ebler, Vlatko Vedral +1
Analytical evidence for the physical relevance of generalized Pauli constraints (GPCs) has recently been provided in [PRL 110, 040404]: Natural occupation numbers $\vecλ\equiv (λ_i…
Efficient Quantum Compression for Ensembles of Identically Prepared Mixed States
Yuxiang Yang, Giulio Chiribella, Daniel Ebler
We present one-shot compression protocols that optimally encode ensembles of identically prepared mixed states into qubits. In contrast to the case of pure-state en…
