Hype, Hope, Moore’s Law, and Quantum Computing; India and France Collaborate
Hype, Hope, Moore’s Law, and Quantum Computing; India and France Collaborate ‘Quantum computing’s trapped between hype and hope … in science you get surprises and what’s useful may not be what we expect now’ Excerpts and salient points ~ + One way to combat the quantum decoherence is supercooling, but it’s impractical for commercialisation. What […]
‘Re-entrant Superconductivity’ in Uranium Ditelluride Promising for Use in Quantum Computers
‘Re-entrant Superconductivity’ in Uranium Ditelluride Promising for Use in Quantum Computers Rare ‘Lazarus superconductivity’ observed in promising, rediscovered material In brief… + Once dismissed by physicists for its apparent lack of interesting physical properties, uranium ditelluride is having its own Lazarus moment. The current study is the second in as many months (both published by […]
Google’s Quantum Supremacy Proves Quantum Computing is Merely ‘Really, Really Hard’
Google’s Quantum Supremacy Proves Quantum Computing is Merely ‘Really, Really Hard’ Why I Called It ‘Quantum Supremacy’ Excerpts and salient points ~ + The quantum supremacy milestone allegedly achieved by Google is a pivotal step in the quest for practical quantum computers. I thought it would be useful to have a word for the era […]
Just SiC. Silicon Carbide Semiconductor Research May Pan Out for Quantum Information Processing
Just SiC. Silicon Carbide Semiconductor Research May Pan Out for Quantum Information Processing Silicon is in the scope for many quantum computing research teams. But what exactly is SiC? To understand the application to quantum computing in this piece, we had to sort it out. From ROHM Semiconductor: “SiC (silicon carbide) is a compound semiconductor […]
Peeking at Schrodinger’s Cat Without Disrupting the Quantum State
Peeking at Schrodinger’s Cat Without Disrupting the Quantum State Can we peek at Schrödinger’s cat without disturbing it? Excerpts and salient points ~ + Their new paper published this month has found that by reading the information observed from a quantum system away from the system itself researchers can determine its state, depending on the […]

Is Quantum Computing Headed for a Quantum Winter?
Is Quantum Computing Headed for a Quantum Winter? Well done report. Points out some of the realities to ‘hype’ and where the quantum computing business stands (or sits). Because Quantum is Coming. Qubit. Beyond quantum supremacy: the hunt for useful quantum computers Selected notes ~ + Today’s quantum machines have at best a few dozen […]
There May Be a Zoo of Non-classical Correlations Different than Bell’s
There May Be a Zoo of Non-classical Correlations Different than Bell’s Viewpoint: Quantum Correlations Take a New Shape Excerpts and salient points ~ + Bell experiments provide perhaps the clearest demonstration of how radically quantum physics departs from classical physics. In such experiments, pairs of quantum particles are prepared in special entangled states and separately […]
