The group of Miguel Navascués at the Institute for Quantum Optics and Quantum Information Vienna (IQOQI-Vienna) is opening two postdoc positions of two years each. The Navascués group works in the interplay between quantum information […]
Quantum 5, 604 (2021). https://doi.org/10.22331/q-2021-12-16-604 We define two dual tensor network representations of the (3+1)d toric code ground state subspace. These two representations, which are obtained by initially imposing either family of stabilizer constraints, are […]
Unlike the jumble of frequencies produced by the light that surrounds us in daily life, each frequency of light in a specialized light source known as a “soliton” frequency comb oscillates in unison, generating solitary […]
Quantum 5, 603 (2021). https://doi.org/10.22331/q-2021-12-16-603 Cryptography with quantum states exhibits a number of surprising and counterintuitive features. In a 2002 work, Barnum et al. argue that these features imply that digital signatures for quantum states […]
Remember IBM’s Watson, the AI Jeopardy! champion? A 2010 promotion proclaimed, “Watson understands natural language with all its ambiguity and complexity.” However, as we saw when Watson subsequently failed spectacularly in its quest to “revolutionize […]
A team led by Prof. Dr. Tobias Schätz, Professor of Atomic and Quantum Physics at the Institute of Physics at the University of Freiburg, Dr. Pascal Weckesser, Fabian Thielemann and colleagues, demonstrate magnetic Feshbach resonances […]
PRESS RELEASE — Rigetti Computing (TQI:Rigetti), a pioneer in hybrid quantum-classical computing, introduced its next-generation “Aspen-M” 80-qubit quantum computer into private beta. Aspen-M is the world’s first commercial multi-chip quantum processor, solving a critical scaling […]
PRESS RELASE – IonQ, Inc. (TQI: IonQ) , a leader in trapped-ion quantum computing, announced the appointment of Inder M. Singh to the IonQ Board of Directors. Singh is the EVP and CFO of Arm, […]
An international team of researchers shows through a concrete theoretical experiment that the prediction by standard complex quantum theory cannot be expressed by its real counterpart and ratifies its need of complex numbers. Their results […]
We had reported last June that Rigetti was working on an 80-qubit processor utilizing multi-chip technology and they have just announced they are now starting to make it available for private beta through the Rigetti […]
