8+ hour, 11+ min ago  (1051+ words) For the first time, a full two-dimensional potential energy surface for water has been generated directly on quantum hardware, mapped over a 32x32 grid. This experimental demonstration, utilising up to 16 qubits, extends quantum molecular simulation beyond simple energy calculations. Combining Sample-based…...

10+ hour, 44+ min ago  (342+ words) Driving quantum heat engines from near-zero to infinite temperature is now theoretically possible, extending the limits of thermodynamic control. This new framework unifies previously separate models, demonstrating how multilevel coherence can both heat and cool a system with unprecedented precision....

23+ hour, 34+ min ago  (856+ words) A 632x632 atom array can now be reconfigured with one-seventh the transport cost of previous methods. This advance, achieved through a planning algorithm that parallelises atom movement, also increases atom capture rates by 32 to 35 per cent. The resulting efficiency gains contribute…...

4+ day, 1+ hour ago  (543+ words) NASA astronaut Jessica Meir is working with the Cold Atom Lab aboard the International Space Station, an investigation that uses chilled atoms to study atomic wave functions and conduct quantum research. The experiment utilizes sensitive fiber optic cables to trap…...

4+ day, 6+ hour ago  (547+ words) Interferometrically enhanced asymmetry in strong-field ionization with bright squeezed vacuum Photoelectron momentum distributions now display asymmetries orders of magnitude greater than those achievable with classical fields of comparable intensity. This control, realised through simulation using bright squeezed vacuum, manipulates ionization…...

4+ day, 9+ hour ago  (656+ words) Rusty is a quantum science nerd. He's been into academic science all his life, but spent his formative years doing less academic things. Now he turns his attention to write about his passion, the quantum realm. He loves all things…...

4+ day, 22+ hour ago  (942+ words) Defining the parity operator for particles beyond bosons and fermions has long relied on incomplete algebraic frameworks. Now, extending Green's triple relations with a newly defined parity operator reveals that n parafermions obey the orthogonal Lie algebra so(2n+2), while n…...

5+ day, 2+ hour ago  (985+ words) Can quantum phases arise not from field strength, but from position along a chain? Analysis of an Ising chain within a quadratic well demonstrates spatially varying quantum phases, a departure from conventional models. This configuration predicts periodic oscillations originating from…...

5+ day, 7+ hour ago  (217+ words) Atom arrays now exhibit strong super- and subradiant emission with a 266nm spacing, smaller than the 841nm wavelength of the light emitted. This surpasses previous limitations of point-like ensembles, accessing a qualitatively new collective behaviour. Such geometrically ordered arrangements demonstrate correlated many-body…...

5+ day, 3+ hour ago  (968+ words) A 25x25 array of trapped atoms now occupies a space achievable in many more laboratories. Previously, building optical tweezer arrays demanded extensive laboratory infrastructure and multiple laser systems. This simplified setup integrates a compact 40cm vacuum system with a single cooling laser,…...
