Superconducting qubits are sensitive to noise - from electromagnetic disturbances, impurities in the material, and even cosmic rays can easily perturb their quantum states and induce errors. From the quantum computer point of view, none of these are desirable. On the other hand, this very sensitivity implies that qubits can be used as highly sensitive sensors for weak fields—such as dark...

High-energy physics (HEP) demands not only experimental probes of known and unknown particles but also an intricate understanding of the theory of gauge fields. At ICEPP, we combine our traditional competency in experimental HEP with a rapidly developing expertise in quantum technologies, both theoretical and experimental, developing multiple research thrusts that cover a wide range of topics...

We explore relations between quantum error correction and gauge theory. They have a conceptual similarity that quantum error correction provides a redundant description of logical qubits in terms of encoded qubits while gauge theory has a redundancy to describe physical states. Motivated by the conceptual similarity and recent demand for efficient ways to put gauge theories on quantum...

We propose a quantum algorithm to efficiently estimate the entanglement asymmetry, a recently introduced measure of symmetry breaking at the subsystem level that plays a key role in the quantum Mpemba effect. Our protocol combines the SWAP test with ideas from quantum phase estimation and requires a number of measurements independent of the system size, making it suitable for large quantum...
