Short qudit triorthogonal codes from doubling
We construct short triorthogonal codes for qudits of odd prime dimension by generalizing doubling, which combines a triorthogonal code with a code admitting a transversal phase gate, and raises the…A compact ultracold strontium experiment
We describe a compact and simplified experimental setup for the production of ultracold strontium atoms.Splitting Probability in Monitored Quantum Dynamics
We consider a continuous-time quantum walk stroboscopically subjected to projective measurements on two distinct targets with sampling time period $τ$.Quantum-Enhanced Matterwave Interferometry in a Ring Waveguide
We propose a quantum-enhanced matter-wave interferometry protocol based on fractional-revival dynamics of a Bose-Einstein condensate in a ring, combined with a controlled interaction quench.Accurate Wichmann-Kroll vacuum polarization calculations with Gaussian basis set
We apply a large Gaussian basis set of size up to $N = 500$ to calculate the all-order Wichmann-Kroll vacuum polarization correction in highly-charged ion.Local distinguishability of five quadripartite orthogonal product states
The local distinguishability of five bipartite and tripartite orthogonal product states (OPSs) has been effectively resolved, while that of five quadripartite OPSs has not yet been effectively…Quantum f-divergences from retrodictive tests: a unifying classical variational principle
The same classical f-divergence admits inequivalent extensions to quantum states.Semiclassical molecular dynamics simulations of electromagnetically induced transparency cooling of 2D and 3D ion crystals in a Penning trap
Motional modes of trapped-ion crystals in Penning traps can now be cooled to near their ground states via electromagnetically induced transparency (EIT) cooling.Encoding a bosonic mode into qubits for simulating boson-matter interactions
We explore the space-time cost of encoding of a bosonic mode into a set of qubits via various encodings, and their resilience to noise.Mamba Quantum Eigensolver (MQE): A Selective State Space Model for Scalable Ground State Simulations in Quantum Chemistry
Predicting molecular electronic structure using Quantum Computing approaches is a challenge in Computational Chemistry.Quantum Charge as a Particle/Antiparticle Label
We show that the concept of particles and antiparticles is related to the Weyl-Heisenberg group $W\!H_3$.Conservation in Every Quantum Measurement Outcome?
In quantum mechanics, conservation laws are usually understood only statistically and only in the context of unitary evolution: during such evolution, if an observable commutes with the Hamiltonian…Teaching quantum mechanics in secondary schools: A qubit-first learning path to Bell's inequalities
Teaching quantum mechanics at the secondary school level remains a major educational challenge.From Traveling Waves to Synthetic Gauge Fields: A Field-Free Route to Superconducting Diode Effect
The superconducting diode effect requires the forward and reverse bias currents to differ, a scenario achieved via inversion and time-reversal symmetries broken together.Superconducting parametric amplifiers based on arrays of unequal Josephson junction elements
Impedance matching is a crucial feature of an amplifier used to increase its instantaneous bandwidth and is typically achieved using static LC resonators.Resource Analysis of Quantum Optimization Algorithms via Variational Methods
Variational Quantum Algorithms (VQAs) are promising approaches for solving combinatorial optimization problems on near-term quantum devices.Finite Classification of Transversal Diagonal Gates Beyond Stabilizer Codes
We establish that transversal diagonal gates on exact qubit codes of distance at least two can be exhaustively classified within a finite search space.International atomic clock comparison achieving $5\times 10^{-18}$ uncertainty
Two single-ion optical clocks, located in the United Kingdom and in Germany, are compared remotely via a 2220\,km long optical fiber link.Meter-scale quantum interconnects between large quantum processors
Modular quantum architecture requires long-distance quantum interconnects to stitch together individual processor modules.Two particle interference: The Hanbury Brown Twiss and Hong Ou Mandel experiments
I discuss two important quantum optics experiments which depend on two particle interference.
