Previously, dependable quantum key distribution relied on fixed infrastructure. Now, a dynamic network utilising drones has demonstrated secure communication over 1. 2km with a key rate of 2.
Previously, the precision of distributed quantum sensing improved only linearly with each repeated measurement. Now, by entangling photons across time itself, a pathway emerges to double the gains wit…
Previously, simulating interacting quantum spins with polar molecules meant controlling only a handful of molecules. Now, coherent dynamics have been demonstrated in mesoscopic arrays, allowing observ…
How many measurements are absolutely needed to fully define a quantum state, given its energy and desired accuracy? This work establishes a limit of n³/ε² measurements for determining an n-mode Gaussi…
Previously, quantum block encoding struggled with matrices containing inherent rank structure, relying on methods designed for sparsity. Now, a dedicated encoding scheme requires just $2\log(N)+7$ anc…
Previously, claims of quantum computers outperforming their classical counterparts often lacked rigorous verification. Now, a detailed analysis reveals the limitations of current classical simulation …
Until recently, quantum computing in chemistry focused on intractable problems, seeking exponential speedups for a select few molecular systems. Now, the emphasis is shifting towards integrating quant…
Previously, assessing disturbance in quantum circuits relied on simplified metrics like relaxation and dephasing times. New work demonstrates these proxies miss vital context-dependent errors arising …
Until now, predicting material behaviour with quantum machine learning has faced a hidden trade-off between model accuracy and computational cost. New work demonstrates that increasing the symmetry wi…
Can complex quantum circuits become untrainable even before any measurable signal emerges? New analysis demonstrates that barren plateaus, regions where learning stops, arise not simply from circuit c…
An order of magnitude increase in logical error rates, compared to previous estimates, reveals the hidden cost of realistic noise in quantum computers. For years, quantum error correction relied on si…
Previously, quantum communication offered no benefit over classical strategies when limited by the number of signals sent without receiver input. Now, entanglement-assisted communication demonstrably …
Horizon Quantum began trading on the Nasdaq today, March 20, under the ticker “HQ”, as the quantum software infrastructure company celebrated with an Opening Bell ceremony. Founder and CEO, Dr. Joe Fi…
Quantum computing is transitioning from research to a technology offering potential competitive advantages for businesses. This article explores how companies can leverage quantum computing for succes…
For decades, the possibility of distinguishing between quantum theory and a simpler, real-number alternative has driven experimental designs. Now, a rigorous analysis reveals that previous attempts to…
Optimal quantum circuit synthesis has moved beyond the twenty-qubit barrier. Previously limited to approximately twenty qubits, this work demonstrates a method capable of synthesising states for a 144…
The UK government announced a £2 billion initiative to accelerate research in quantum computing, inviting proposals for prototypes. Over £1 billion in private capital has already fueled UK quantum sta…
