Finding an elusive elementary particle is more viable than ever after an international team of scientists conducted the first experiment to explore magnetic monopoles using the Large Hadron Collider. Click to rate this post! [Total: […]
Quantum 6, 642 (2022). https://doi.org/10.22331/q-2022-02-02-642 With increasing subsystem size and energy, bipartite entanglement entropies of energy eigenstates cross over from the groundstate scaling to a volume law. In previous work, we pointed out that, when […]
Researchers have succeeded in forming a control loop consisting of two quantum systems separated by a distance of one meter. Within this loop, one quantum system — a vibrating membrane — is cooled by the […]

We’ve all experienced the principle of feedback—for example, when we use a thermostat in conjunction with a heating system to regulate indoor temperature. The thermostat measures the current temperature, compares it with the target value […]
Quantum 6, 641 (2022). https://doi.org/10.22331/q-2022-02-02-641 Negative quantum conditional entropy states are key ingredients for information theoretic tasks such as superdense coding, state merging and one-way entanglement distillation. In this work, we ask: how does one […]
Quantum 6, 640 (2022). https://doi.org/10.22331/q-2022-02-02-640 We consider the problem of learning stabilizer states with noise in the Probably Approximately Correct (PAC) framework of Aaronson (2007) for learning quantum states. In the noiseless setting, an algorithm […]
