Paper Resource Efficient Boolean Function Solver on Quantum Computer Xiang Li, Hanxiang Shen, Weiguo Gao, and Yingzhou Li, Quantum 8, 1500 (2024). Nonlinear boolean equation systems play an important role in a wide range of applications. Grover's algorithm is one of the best-known quantum search algorithms in solving the nonlinear bool… Paper Quantum teleportation implies symmetry-protected topological order Yifan Hong, David T. Stephen, and Aaron J. Friedman, Quantum 8, 1499 (2024). We constrain a broad class of teleportation protocols using insights from locality. In the "standard" teleportation protocols we consider, all outcome-dependent unitaries are Pauli operators… Paper Decoding algorithms for surface codes Antonio deMarti iOlius, Patricio Fuentes, Román Orús, Pedro M. Crespo, and Josu Etxezarreta Martinez, Quantum 8, 1498 (2024). Quantum technologies have the potential to solve certain computationally hard problems with polynomial or super-polynomial speedups when compared to classical methods. Unfortunately, the uns… Paper Quantum lozenge tiling and entanglement phase transition Zhao Zhang and Israel Klich, Quantum 8, 1497 (2024). While volume violation of area law has been exhibited in several quantum spin chains, the construction of a corresponding ground state in higher dimensions, entangled in more than one direct… Paper Implementing any Linear Combination of Unitaries on Intermediate-term Quantum Computers Shantanav Chakraborty, Quantum 8, 1496 (2024). We develop three new methods to implement any Linear Combination of Unitaries (LCU), a powerful quantum algorithmic tool with diverse applications. While the standard LCU procedure requires… Paper Iteration Complexity of Variational Quantum Algorithms Vyacheslav Kungurtsev, Georgios Korpas, Jakub Marecek, and Elton Yechao Zhu, Quantum 8, 1495 (2024). There has been much recent interest in near-term applications of quantum computers, i.e., using quantum circuits that have short decoherence times due to hardware limitations. Variational qu… Paper Branching States as The Emergent Structure of a Quantum Universe Akram Touil, Fabio Anza, Sebastian Deffner, and James P. Crutchfield, Quantum 8, 1494 (2024). Quantum Darwinism builds on decoherence theory to explain the emergence of classical behavior in a fundamentally quantum universe. Within this framework we prove two crucial insights about t… Paper Quantum-classical tradeoffs and multi-controlled quantum gate decompositions in variational algorithms Teague Tomesh, Nicholas Allen, Daniel Dilley, and Zain Saleem, Quantum 8, 1493 (2024). The computational capabilities of near-term quantum computers are limited by the noisy execution of gate operations and a limited number of physical qubits. Hybrid variational algorithms are… Paper Mixed-state additivity properties of magic monotones based on quantum relative entropies for single-qubit states and beyond Roberto Rubboli, Ryuji Takagi, and Marco Tomamichel, Quantum 8, 1492 (2024). We prove that the stabilizer fidelity is multiplicative for the tensor product of an arbitrary number of single-qubit states. We also show that the relative entropy of magic becomes additive… Paper Differentiating and Integrating ZX Diagrams with Applications to Quantum Machine Learning Quanlong Wang, Richie Yeung, and Mark Koch, Quantum 8, 1491 (2024). ZX-calculus has proved to be a useful tool for quantum technology with a wide range of successful applications. Most of these applications are of an algebraic nature. However, other tasks th… Paper Repeated measurements on non-replicable systems and their consequences for Unruh-DeWitt detectors Nicola Pranzini, Guillermo García-Pérez, Esko Keski-Vakkuri, and Sabrina Maniscalco, Quantum 8, 1490 (2024). The Born rule describes the probability of obtaining an outcome when measuring an observable of a quantum system. As it can only be tested by measuring many copies of the system under consid… Paper (Almost-)Quantum Bell Inequalities and Device-Independent Applications Yuan Liu, Ho Yiu Chung, and Ravishankar Ramanathan, Quantum 8, 1489 (2024). Investigations of the boundary of the quantum correlation set have gained increased attention in recent years. This is done through the derivation of quantum Bell inequalities, which are rel… Paper Topological photon pumping in quantum optical systems Mathias B. M. Svendsen, Marcel Cech, Max Schemmer, and Beatriz Olmos, Quantum 8, 1488 (2024). We establish the concept of topological pumping in one-dimensional systems with long-range couplings and apply it to the transport of a photon in quantum optical systems. In our theoretical… Paper Quantum Multiple Eigenvalue Gaussian filtered Search: an efficient and versatile quantum phase estimation method Zhiyan Ding, Haoya Li, Lin Lin, HongKang Ni, Lexing Ying, and Ruizhe Zhang, Quantum 8, 1487 (2024). Quantum phase estimation is one of the most powerful quantum primitives. This work proposes a new approach for the problem of multiple eigenvalue estimation: Quantum Multiple Eigenvalue Gaus… Paper Stochastic Thermodynamics at the Quantum-Classical Boundary: A Self-Consistent Framework Based on Adiabatic-Response Theory Joshua Eglinton, Federico Carollo, Igor Lesanovsky, and Kay Brandner, Quantum 8, 1486 (2024). Microscopic thermal machines promise to play an important role in future quantum technologies. Making such devices widely applicable will require effective strategies to channel their output… Paper Relating Wigner’s Friend Scenarios to Nonclassical Causal Compatibility, Monogamy Relations, and Fine Tuning Yìlè Yīng, Marina Maciel Ansanelli, Andrea Di Biagio, Elie Wolfe, David Schmid, and Eric Gama Cavalcanti, Quantum 8, 1485 (2024). Nonclassical causal modeling was developed in order to explain violations of Bell inequalities while adhering to relativistic causal structure and $faithfulness$—that is, avoiding fine-tuned… Posts navigation Older posts Quantum is an open-access peer-reviewed journal for quantum science and related fields.
