New paper by Jochym-O’Connor, Kubica and Yoder – Disjointness of Stabilizer Codes

Stabilizer codes are among the most successful quantum error-correcting codes, yet they have important limitations on their ability to fault tolerantly compute. In a recent paper by Sherman Fairchild Postdoctoral Scholar Tomas Jochym-O'Connor, IQIM alum Alex Kubica and Theodore Yoder introduce a new quantity, the disjointness of the stabilizer code, which, roughly speaking, is the [...]

Thermodynamics of computing: New article by Philippe Faist and Renato Renner

Computers need energy to operate: Have you ever noticed that when rendering graphics or performing other computationally expensive tasks, your laptop heats up and drains its battery? Even though technological improvements have greatly increased the energy efficiency of computer components over the years while making them ever faster, heat dissipation remains one of the major [...]

Quasiprobability behind the out-of-time-ordered correlator, new paper by Yunger Halpern, Swingle and Dressel

A new paper by Nicole Yunger Halpern, Brian Swingle and Justin Dressel combines the out-of-time-ordered correlator (OTOC) and the Kirkwood-Dirac (KD) quasiprobability. Quantum circuit for inferring the coarse-grained OTOC quasiprobability A from weak measurements. [Fig. 3] Two topics, evolving rapidly in separate fields, were combined recently: the out-of-time-ordered correlator (OTOC) signals quantum-information scrambling in [...]

Remembering Stephen Hawking’s Greatest Scientific Accomplishment — and My Famous Bet Against Him

John Preskill's thoughts about his colleague and friend, Stephen Hawking appear in Time Magazine. While his scientific accomplishments alone would suffice to ensure an enduring legacy, Stephen Hawking also became one of the world’s most successful popularizers of science. Stephen firmly believed that the quest for a complete theory of the universe should be accessible [...]

New work by Vidick and collaborators featured in Nature Communications

A new paper, Practical device-independent quantum cryptography via entropy accumulation by Rotem Arnon-Friedman, Frédéric Dupuis, Omar Fawzi, Renato Renner, Thomas Vidick is in the January 31 issue of Nature Communications. Conventional quantum cryptography is already well developed both in theory and experiments. This is not the case, however, for device-independent quantum cryptography, which is the [...]
