High-fidelity parallel entangling gates in atom arrays

Recently, neutral-atom arrays have emerged as a promising platform for quantum computing. Atom arrays are highly flexible and reconfigurable, allowing coherent control over hundreds of qubits and connectivity between any qubits in the array. The main outstanding challenge of using atom arrays has been to reduce errors in entangling operations, which rely on highly-excited atomic...

Scalable Quantum Memory Control in Photonic Circuits

In a study published in “Nano Letters,” MIT and MITRE researchers describe an important advance in controlling spin quantum memories in photonic circuits. Their paper, “Selective and Scalable Control of Spin Quantum Memories in a Photonic Circuit,” offers a new approach for individual-qubit control even when the system is “under-actuated” — i.e., the number of...

Programmable Quantum Simulators Meet Quantum Chemistry

In an interdisciplinary collaborative effort, a team of CUA members in the Yelin, Lukin, and Yao groups joined forces with computational quantum chemists in Martin Head-Gordon’s group (UC Berkeley) to develop a novel approach to simulate quantum properties of molecules and materials on state-of-the-art atomic quantum processors. Quantum chemistry is seen as a promising potential...

Quantum-computing approach uses single molecules as qubits for first time

Platforms based on molecules manipulated using ‘optical tweezers’ might be able to perform complex physics calculations. Physicists have taken the first step towards building quantum computers out of individual molecules trapped with laser devices called optical tweezers. Two teams report their results in Science on 7 December in both cases making pairs of calcium monofluoride...

Building Big Quantum Computers by Connecting Smaller Ones

Building quantum computers that can function despite their inherently noisy components is a long-standing goal for physicists. Quantum error correcting codes promise to make this possible, but to use them, physicists need to carefully choreograph the interactions between large numbers of qubits. Such scaling to large numbers of qubits is generally anticipated to require connecting...

Self-correcting quantum computers within reach?

Quantum computers promise to reach speeds and efficiencies impossible for even the fastest supercomputers of today. Yet the technology hasn’t seen much scale-up and commercialization largely due to its inability to self-correct. Quantum computers, unlike classical ones, cannot correct errors by copying encoded data over and over. Scientists had to find another way. Now, a new...
