IBM Quantum Pricing Models. Credit: IBM IBM has added a new Pay-As-You-Go pricing model to their quantum cloud service. Previously, a user was either in the Free tier that would allow them to access the […]
Colorado has a reputation for being a quantum ecosystem hotspot and a recent panel discussion further bolstered this image. It was hosted by JILA, a world-leading physics institute created by a partnership between the University […]
Lawrence Berkeley National Laboratory physicists Christian Bauer, Marat Freytsis and Benjamin Nachman have leveraged an IBM Q quantum computer through the Oak Ridge Leadership Computing Facility’s Quantum Computing User Program to capture part of a […]

Quantum 6, 688 (2022). https://doi.org/10.22331/q-2022-04-13-688 Evaluating an expectation value of an arbitrary observable $Ain{mathbb C}^{2^ntimes 2^n}$ through naïve Pauli measurements requires a large number of terms to be evaluated. We approach this issue using a […]
Highly energetic particles called muons are ever present in the atmosphere and pass through even massive objects with ease. Sensitive detectors installed along the Tokyo Bay tunnel measure muons passing through the sea above them. […]
Quantum 6, 687 (2022). https://doi.org/10.22331/q-2022-04-13-687 We study the correlation clustering problem using the quantum approximate optimization algorithm (QAOA) and qudits, which constitute a natural platform for such non-binary problems. Specifically, we consider a neutral atom […]
Quantum 6, 686 (2022). https://doi.org/10.22331/q-2022-04-13-686 Quantum coupling between mechanical oscillators and atomic gases generating entanglement has been recently experimentally demonstrated using their subsequent interaction with light. The next step is to build a hybrid atom-mechanical […]
Quantum 6, 685 (2022). https://doi.org/10.22331/q-2022-04-13-685 Fluctuation theorems allow one to make generalised statements about the behaviour of thermodynamic quantities in systems that are driven far from thermal equilibrium. In this article we use Crooks’ fluctuation […]
In August 1883, a mountainous island in Indonesia named Krakatau, or Krakatoa, self-destructed. Episodic volcanic eruptions crescendoed in an explosion that sent debris 80 kilometers high and smothered 800,000 square kilometers of Earth’s surface in […]
