The quantum nature of the gravitational field has been an open question for nearly 100 years. The simplest question one could ask is whether the gravitational field itself is a quantum degree of freedom. Here we propose a test of this idea.

Increasingly complex quantum computing schemes require small-scale solutions for precise qubit control and the isolation of quantum circuits. Addressing this problem is critical for the prospect of future quantum computers.

In March 2019, our group suggested using high-precision optomechanical sensors to search for the minute gravitational signature of passing dark matter particles.

We propose a technique to suppress error in simulating physics on a quantum computer. Our technique works by manipulating the errors from different steps of the simulation such that they interfere destructively and thus cancel out each other.

Electrons confined in arrays of semiconductor nanostructures, called quantum dots (QDs), are a candidate system to realize qubits—the fundamental components of quantum computers.
