The rate at which quantum computing is hitting the media stream is ever-increasing. This piece is a collection of recent articles and reports covering various aspects of quantum computing from the lens of science and research. Mea Cubitt

Technical Perspective: On Proofs, Entanglement, and Games | What is a proof? Philosophers and mathematicians have pondered this question for centuries. Theoretical computer science offers a rigorous handle on this deep question. One can think of a proof as a two-player game: an all-powerful though un-trusted prover who provides a proof of the statement, and a computationally weak verifier who needs only to verify it. In fact, NP problems can be presented exactly in this verifier-prover language. Viewing proofs as games turned out to be remarkably fruitful. For example, interactive proofs were invented, resembling Socratic dialogues; these are games in which the prover and verifier exchange (possibly randomized) messages. And, why just one prover? In multi-prover interactive proofs (MIP) several non-communicating provers are involved. This gave birth to beautiful concepts such as zero knowledge and probabilistically checkable proofs (PCPs) with immense impact not only theoretically but also in practice, for example, in digital currency.  Source: COMMUNICATIONS OF THE ACM.   Technical Perspective: On Proofs, Entanglement, and Games…

Quantum Collaboration | A new collaboration between UC Santa Barbara researchers and Cisco Systems aims to push the boundaries of quantum technologies. Assistant professors Yufei Ding and Galan Moody have received research awards from the technology giant to work with its new Quantum Research Team, which was formed to pursue the research and development required to turn quantum hardware, software, and applications into broadly used technologies.   Source: UC SANTA BARBARA Engineering.   Quantum Collaboration…

Exotic magnetic states on the nanoscale | An international research team, led by scientists from the EMPA (Zurich) and the International Iberian Nanotechnology Laboratory, which has researchers from the UPV/EHU, has succeeded in building chains of quantum magnets made of nanographene that capture the essence of one of the core models of quantum magnetism. The team’s results (Nature, “Observation of fractional edge excitations in nanographene spin chains”) have implications for understanding quantum magnetism on the nanoscale and may open the door to building quantum computers.  Source: nanowerk.   Exotic magnetic states on the nanoscale…

The revolutionary factor that brings quantum computing closer to the PC | There is no doubt that quantum computing is one of the potential futures of computing, but for it to be a commercially viable reality, different barriers must be overcome. Well, one of them known as Full Spin Qubit has finally been overcome, so little by little this new way of understanding computing is taking shape to reach the PC in the future. Current computing is composed of logic gates in which each bit can be in two different positions that we represent as 0 or 1 as it is a binary system. Qubits go beyond this paradigm and promise to change the foundations of computing through concepts that come from a discipline of science: quantum physics.  Source: TechUnwrapped.   The revolutionary factor that brings quantum computing closer to the PC…
