Continuous Operation of a 3,000-Qubit System

Neutral atoms are a promising platform for quantum science, enabling advances in areas ranging from quantum simulations and computation to metrology, atomic clocks, and quantum networking. However, atom loss during operation typically limits these systems to function in a pulsed mode, preventing them from completing extended calculations. If neutral atom systems could function continuously, researchers...

New technique moves thousands of atoms at once in three dimensions

Arrays of individual atoms, each held in place by a tightly focused laser beam called an optical tweezer, have become a leading platform for quantum computing, quantum simulation, and precision measurement. One of the most powerful features of this platform is that each atom can be moved independently of the others, for example to arrange...

Language models discover more efficient reversible quantum circuits

Much of the cost of quantum algorithms lies in classical functions compiled into reversible circuits. Efficient classical algorithms often lose their advantage in this setting, because a circuit cannot branch on superposed data and must retain intermediate results until it can uncompute them. Removing this overhead can require redesigning the algorithm, data representation and uncomputation...

Geometry-aware neural decoder

Quantum low-density parity-check (qLDPC) codes promise to protect quantum information with far fewer physical qubits than the surface code. Realizing this promise requires a classical decoder that interprets error syndromes both accurately and in real time, and no existing decoder does both. In this work, we introduce Cascade, a convolutional neural network decoder built around...

Analog Quantum Simulators

Analog quantum simulators use the continuous evolution of a controlled quantum system to explore quantum phenomena that can be difficult to calculate on an classical computer. But the delicate quantum information that makes them useful is vulnerable to noise. Protecting that information while preserving its desired evolution is a central challenge. In a theoretical study,...

High-Fidelity Entanglement of Molecules through Geometric Control

Reconfigurable tweezer arrays of ultracold polar molecules are a promising and rapidly developing platform for quantum computing, simulation, and precision measurement. Pairs of molecules in different rotational states can interact through a dipolar interaction, which can be used to generate entangled states of molecules. The strength and sign of the interaction depends on the distance...

Semeghini Group Introduces Two-Element Rb-Yb Quantum Platform

There are many neutral atom-based quantum computers within the CUA and all over the world, with researchers striving to improve on the length and complexity of computations achievable on quantum hardware. These goals often involve innovating on the physical hardware design of the quantum computer. One approach is a ‘dual-species’ architecture, which uses individual atoms...

Quantum Precision Measurement for Fundamental Physics

What governs the laws of the most fundamental particles? Why is the universe made of matter, not antimatter? The Fan group is developing an experiment with radioactive thorium monofluoride molecular ions, ²²⁹ThF⁺, to search for new fundamental interactions that could lead to the discovery of new particles and help explain this. Our sensor is the...

One broken symmetry opens a path to universal quantum control

A new theory identifies what globally driven quantum systems need to become fully controllable. In a Rydberg-atom experiment, optimized pulses also create an interaction involving three atoms at once. The study by Hong-Ye Hu and colleagues is forthcoming in Nature Physics. The linked manuscript is the authors’ preprint. Many quantum simulators use a small number...
