It is for the first time that quantum simulation for high-energy physics (HEP) is studied in the
US decadal particle-physics community planning, and in fact until recently, this was not …

During the last ten years, superconducting circuits have passed from being interesting
physical devices to becoming contenders for near-future useful and scalable quantum …

We describe and benchmark a new quantum charge-coupled device (QCCD) trapped-ion
quantum computer based on a linear trap with periodic boundary conditions, which …

The ambition of harnessing the quantum for computation is at odds with the fundamental
phenomenon of decoherence. The purpose of quantum error correction (QEC) is to …

Practical quantum computing will require error rates well below those achievable with
physical qubits. Quantum error correction, offers a path to algorithmically relevant error rates …

Quantum computers hold the promise of solving computational problems that are intractable
using conventional methods. For fault-tolerant operation, quantum computers must correct …

Quantum error correction (QEC) aims to protect logical qubits from noises by using the
redundancy of a large Hilbert space, which allows errors to be detected and corrected in real …

The ability to engineer parallel, programmable operations between desired qubits within a
quantum processor is key for building scalable quantum information systems,. In most state …

We report on an elementary quantum network of two atomic ions separated by 230 m. The
ions are trapped in different buildings and connected with 520 (2) m of optical fiber. At each …

Quantum computers can be protected from noise by encoding the logical quantum
information redundantly into multiple qubits using error-correcting codes,. When …
