Solving the Wiring Problem in Quantum Computers

It’s the “Wiring” That’s Tricky in Quantum Computing. ‘While large-scale quantum computers remain in the domain of science fiction, a joint team from Japan announced Thursday that it has been able to take a small but crucial step in pursuit of this advanced goal. NEC, the Institute of Physical and Chemical Research, or RIKEN, and […]

Entanglement Sudden Death (ESD) Observed for the First Time

Entanglement dies a sudden death. ‘A strange quantum phenomenon that could be a stumbling block to building quantum computers has been observed for the first time by physicists in Brazil. Known as entanglement sudden death (ESD), it involves the rapid decay of the “entangled” pairs of particles that will be central to the operation of […]

D-Wave’s Orion: The World’s First Commercial Quantum Computer?

A Giant Leap Forward in Computing? Maybe Not. ‘Did D-Wave Systems achieve the incredible — a startling advance in computing that would radically expand human capacities for industrial activity and scientific discovery, long before experts believed it possible? It says it did, and many concurred. According to the company and publications like The Economist, D-Wave, […]

Quantum Mechanics, 1925-1927 – Heisenberg: The Uncertainty Principle

Quantum Mechanics, 1925-1927 – Heisenberg: The Uncertainty Principle. “The more precisely the position is determined, the less precisely the momentum is known in this instant, and vice versa”. ‘This is a succinct statement of the “uncertainty relation” between the position and the momentum (mass times velocity) of a subatomic particle, such as an electron. This […]

Another Step Toward Quantum Computers

A Quantum (Computer) Step. ‘A University of Utah physicist took a step toward developing a superfast computer based on the weird reality of quantum physics by showing it is feasible to read data stored in the form of the magnetic “spins” of phosphorus atoms.“Our work represents a breakthrough in the search for a nanoscopic [atomic […]
