Two microseconds is now all it takes to prepare Fock states up to five photons and perform a single-photon SWAP, a speed previously unattainable without sacrificing cavity isolation. Conventional meth…
Over a thousand entangled operations have unlocked a new scale in quantum simulation. Until now, digital quantum simulations of particle physics have been restricted to one-plus-one dimensions or limi…
Utilising $1540$ entangling gates, a quantum computer has simulated string-breaking dynamics on a $5 \times 4$ lattice, exceeding the scale of previous experiments. This demonstration required a speci…
A quantum computer requiring fewer than 60 logical qubits can now process data sets that would necessitate machines exponentially larger to achieve comparable performance. This represents a four to si…
Trotterization of many-body quantum systems typically suffers a convergence penalty of 1/4, even without simplifying the problematic Coulomb interaction. Now, a rigorous analysis confirms this rate fo…
Previously limited to functions defined within a finite domain, inverse Laplace and Mellin integral transforms are now extended to encompass arguments within [0, ∞[. This modification unlocks applicat…
Establishing a clear boundary between simulations and genuine quantum computation has long been a challenge. This work identifies a complexity phase transition in continuous-variable cluster states, r…
Analysis of State Teleportation using Noisy Quantum Gates Until now, assessing the impact of multiple, independent sources of quantum error required separate analyses for each. This work presents a un…
Quantum simulations of collective neutrino oscillations now require fewer qubits than previously possible, offering a potential route to modelling complex astrophysical phenomena. These new algorithms…
Circuits for complex quantum calculations are typically limited by their size and intricacy. Now, an automated design framework has achieved the Full-CI limit for molecular hydrogen using shallower ci…
Testing whether a directed network possesses a specific property now requires substantially fewer steps thanks to a new quantum algorithm. Previously, classical methods demanded a number of queries sc…
Extending ground-state cooling beyond single dimensions, this work simultaneously cools six motional modes of two levitated nanoparticles. Previous methods achieved cooling along one, two, or three di…
An Area Under the Curve of 0. 995 now distinguishes successful from failed Belief Propagation decoding for quantum error correction, a performance eclipsing all previous syndrome-based prediction meth…
Calculating a seemingly intractable quantum effect has become surprisingly simple, with a two-loop correction now derivable from a one-loop calculation. This advance bypasses a computationally intensi…
Four or more interacting Rydberg atoms, previously unamenable to detailed analysis, now yield their dark-state secrets through an extended arrowhead-matrix method. This work bridges a gap in understan…
