How to Quantify the Uncertainty of “Instantaneously”

‘We have broken speed of light’. ‘A pair of German physicists claim to have broken the speed of light – an achievement that would undermine our entire understanding of space and time. According to Einstein’s special theory of relativity, it would require an infinite amount of energy to propel an object at more than 186,000 […]

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 […]

Interactive Animations: Visual Quantum Mechanics

Visual Quantum Mechanics – Explorations of the Quantum World for Non-Science Students. ‘The Visual Quantum Mechanics project, funded by the National Science Foundation, involves the development of instructional units that introduce quantum physics to high school and college students who do not have a background in modern physics or higher level math. To reach these […]

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 […]
