Insider Brief QuEra announced today that Alex Keesling will transition from CEO to take on a new role in leading QuEra’s efforts. The Board of Directors appointed board member Andy Ory as the acting CEO […]
Insider Brief Entanglement is essential for quantum computers and to transmit quantum information in a future quantum network. A team of Max Planck researchers has entangled resting qubits with flying qubits in the form of […]
With just the flick of a switch, quantum materials can undergo drastic changes. One notable example is the insulator-to-metal transition, a reversible physical phenomenon in which a material shifts from an insulating state, which will […]
Quantum 8, 1411 (2024). https://doi.org/10.22331/q-2024-07-15-1411 The quantum simulation of magnetism in trapped-ion systems makes use of the crystal vibrations to mediate pairwise interactions between spins, which are encoded in the internal electronic states of the […]
Quantum 8, 1410 (2024). https://doi.org/10.22331/q-2024-07-15-1410 Using near-term quantum computers to achieve a quantum advantage requires efficient strategies to improve the performance of the noisy quantum devices presently available. We develop and experimentally validate two efficient […]
Quantum 8, 1409 (2024). https://doi.org/10.22331/q-2024-07-15-1409 Digital quantum simulation has broad applications in approximating unitary evolution of Hamiltonians. In practice, many simulation tasks for quantum systems focus on quantum states in the low-energy subspace instead of […]
Sometimes mathematicians try to tackle a problem head on, and sometimes they come at it sideways. That’s especially true when the mathematical stakes are high, as with the Riemann hypothesis, whose solution comes with a […]
A study in Nature Physics introduces a novel method for generating quantum entanglement using a quantum dot, which violates the Bell inequality. This ultra-low power method could pave the way for scalable and efficient quantum […]
