Existing methods for quantifying quantum coherence relied on either Wigner-Yanase or Wigner-Yanase-Dyson skew information, but a unified approach remained elusive. This work introduces metric adjusted…
How can we accurately predict elastic wave propagation without knowing precisely how many quantum gates a simulation will require? Explicit gate complexity estimates for the three-dimensional elastic …
Operational determination of whether a quantum state exhibits classically-forbidden negativity in its Wigner function was previously incomplete. Now, a direct link between readily measurable coherent …
Reducing model size while simultaneously improving computational performance represents a rare achievement in tackling the notoriously difficult Traveling Salesman Problem. This work delivers precisel…
Period-doubling oscillations now persist for system sizes previously thought to preclude them, and last a time exponential in the system’s size. This contrasts with earlier work on quantum scars, wher…
Unitary realizations of synchronizing automata now extend beyond simple recognition tasks to encompass synchronization, a capability previously absent in quantum finite automata. Unlike classical coun…
A shuttling fidelity of 99. 99 ±0. 007%, maintained during 10μm transport at 20m/s, represents a substantial leap towards practical quantum computation.
Lower error rates in quantum linear system solvers have historically demanded increased computational complexity. New algorithms, however, achieve up to an order of magnitude improvement in accuracy c…
Until now, validating the extended Su-Schrieffer-Heeger model relied on computationally intensive methods. Exact analytical expressions for edge states have been derived, confirming the model’s behavi…
High-sensitivity windows for quantum measurement are now extended by over an order of magnitude, transforming previously damped oscillations into a smooth, easily trackable trajectory. By combining en…
Device-independent quantum cryptography traditionally assumes complete security, yet practical devices inevitably reveal some information. This analysis moves beyond that ideal by quantifying secure c…
Within 170 seconds, a complex optimisation problem with 500 interacting variables can now be solved using a new quantum framework. This contrasts sharply with conventional methods, which struggle with…
Until now, calculations of how photons and matter interact in chiral waveguide quantum electrodynamics have been incomplete, limited to only a portion of possible energies. This work reveals a complet…
Operator growth, previously understood as a predictable flow within quantum systems, now appears fundamentally altered by environmental influence. This work demonstrates that coupling to an environmen…
Sixteen distinct channels of single photons, precisely spaced 25GHz apart, now carry quantum information thanks to a newly demonstrated network hub. Unlike previous methods, this system achieves polar…
Topological insulators now possess a single, consistent description applicable to both static materials and those driven by periodic energy inputs. Previous methods failed to bridge this divide, or re…
Exponential failure rates plague classical optimisation, yet harnessing quantum power for complex searches has remained elusive. Now, a new framework prevents this collapse and reduces the classical c…
A quantum strategy, utilising a single entangled pair, now outperforms the classical optimum for coordinating frequency selection, regardless of spectrum size. This advantage, achieving 5. 4% improvem…
Yuval Boger interviews Tom Darras, CEO and co-founder of Welinq. They discuss how quantum networking uses shared entanglement to interconnect quantum processors, enabling modular scale-out clusters an…
Insider Brief A quantum computer powerful enough to break the cryptography that secures Bitcoin and Ethereum will eventually be built, and the blockchain industry is running out of time to do somethin…
Insider Brief Mandeville Ventures Inc. has signed a definitive agreement to merge with quantum cybersecurity firm Quantropi Inc., advancing a previously announced transaction that would take the Ottaw…
Insider Brief PRESS RELEASE — QuantumCore Inc. (CSE: QNCR) (“QuantumCore” or the “Company”) today announced a deepened collaboration with the Institute for Quantum Computing (IQC) at the University of…
Insider Brief Most encryption protecting online banking, government communications, medical records, and corporate infrastructure relies on a mathematical assumption – certain problems are too computa…
Insider Brief A new study warns that the exotic raw materials powering quantum computers, sensors and secure communications are dangerously concentrated in the hands of a few countries — mostly China …
