Multi-target quantum walk search on Johnson graph
Pulak Ranjan Giri·Oct 6, 2025
The discrete-time quantum walk on the Johnson graph $J(n,k)$ is a useful tool for performing target vertex searches with high success probability. This graph is defined by $n$ distinct elements, with vertices being all the \(\binom{n}{k}\) $k$-elemen...
Quantum walk search based edge detection of images
Pulak Ranjan Giri, Rei Sato, Kazuhiro Saito·Oct 6, 2025
Quantum walk has emerged as an essential tool for searching marked vertices on various graphs. Recent advances in the discrete-time quantum walk search algorithm have enabled it to effectively handle multiple marked vertices, expanding its range of a...
Quantum precomputation: parallelizing cascade circuits and the Moore-Nilsson conjecture is false
Adam Bene Watts, Charles R. Chen, J. William Helton +1 more·Oct 6, 2025
Parallelization is a major challenge in quantum algorithms due to physical constraints like no-cloning. This is vividly illustrated by the conjecture of Moore and Nilsson from their seminal work on quantum circuit complexity [MN01, announced 1998]: u...
Quantum Computing as a Service - a Software Engineering Perspective
Aakash Ahmad, Muhammad Waseem, Bakheet Aljedaani +3 more·Oct 6, 2025
Quantum systems have started to emerge as a disruptive technology and enabling platforms - exploiting the principles of quantum mechanics via programmable quantum bits (QuBits) - to achieve quantum supremacy in computing. Academic research, industria...
Atomtronic routing of dipolar bosons in a four-well star potential
Karin Wittmann W., Leandro H. Ymai, Genessi Sá Neto +1 more·Oct 5, 2025
The ability to precisely control and predict the evolution of quantum states is a fundamental requirement for advancing quantum technologies. Here, we develop tunable atomic routing protocols based on an integrable model of dipolar bosons confined in...
Electromagnetic instability of vacuum with instantons in the holographic plasma
Shao-cheng Hou, Si-wen Li·Oct 5, 2025
Using the gauge-gravity duality, we study the electromagnetic instability of vacuum with instantons in holographic plasma. The model we employ is the D(-1)-D3 brane system in which the D(-1)-branes correspond to the instantons in holography. To take ...
Integrable Floquet Time Crystals in One Dimension
Rahul Chandra, Mahbub Rahaman, Soumyabroto Majumder +2 more·Oct 5, 2025
We demonstrate the realization of a Discrete Time-Crystal (DTC) phase in a family of periodically driven, one-dimensional quadratic lattice Hamiltonians that can be obtained using spin chains. These interactions preserve integrability while opening c...
Time-resolved characterization of pulsed squeezed light from a strongly driven silicon nitride microresonator
Emanuele Brusaschi, Marco Liscidini, Matteo Galli +2 more·Oct 5, 2025
Silicon nitride microresonators driven by strong pump pulses can generate squeezed light in a dominant spectral-temporal mode, a central resource for continuous-variable quantum computation. In the high parametric gain regime, several effects, includ...
Filtered Quantum Phase Estimation
Gwonhak Lee, Minhyeok Kang, Jungsoo Hong +2 more·Oct 5, 2025
Accurate state preparation is a critical bottleneck in many quantum algorithms, particularly those for ground state energy estimation. Even in fault-tolerant quantum computing, preparing a quantum state with sufficient overlap to the desired eigensta...
X-states of a qubit pair of double classicality
Arsen Khvedelidze, Dimitar Mladenov, Astghik Torosyan·Oct 5, 2025
A special class of states of 2-qubits which are simultaneously separable and have positive semidefinite Wigner functions is described.
Higher symmetry breaking and non-reciprocity in a driven-dissipative Dicke model
Jacquelyn Ho, Yue-Hui Lu, Tai Xiang +3 more·Oct 5, 2025
Higher symmetries in interacting many-body systems often give rise to new phases and unexpected dynamical behavior. Here, we theoretically investigate a variant of the Dicke model with higher-order discrete symmetry, resulting from complex-valued cou...
Turning Down the Noise: Power-Law Decay and Temporal Phase Transitions
Lieuwe Bakker, Suvendu Barik, Vladimir Gritsev +1 more·Oct 5, 2025
We determine the late-time dynamics of a generic spin ensemble with inhomogeneous broadening - equivalently, qubits with arbitrary Zeeman splittings - coupled to a dissipative environment with strength decreasing as $1/t$. The approach to the steady ...
Operational Quasiprobability in Quantum Thermodynamics: Work Extraction by Coherence and Non-joint Measurability
Jeongwoo Jae, Junghee Ryu, Hoon Ryu·Oct 5, 2025
We employ the operational quasiprobability (OQ) as a work distribution, which reproduces the Jarzynski equality and yields the average work consistent with the classical definition. The OQ distribution can be experimentally implemented through the en...
Quantum Error Correction with Superpositions of Squeezed Fock States
Yexiong Zeng, Fernando Quijandría, Clemens Gneiting +1 more·Oct 5, 2025
Bosonic codes, leveraging infinite-dimensional Hilbert spaces for redundancy, offer great potential for encoding quantum information. However, the realization of a practical continuous-variable bosonic code that can simultaneously correct both single...
Quantum computing for heavy-ion physics: near-term status and future prospects
João Barata·Oct 5, 2025
We discuss recent advances in applying Quantum Information Science to problems in high-energy nuclear physics. After outlining key developments, open challenges, and emerging connections between these disciplines, we highlight recent results on the s...
Qubit entanglement from forward scattering
Kamila Kowalska, Enrico Maria Sessolo·Oct 5, 2025
In the context of entanglement in relativistic $2\to 2$ scattering described by a perturbative $S$-matrix, we derive analytically the concurrence for a mixed final state of two qubits corresponding to a discrete quantum number of the scattered partic...
