School-level physics tells us that if you give an atom energy, you can "excite" it: you can boost an electron inside it to a higher energy level. When the electron returns to a lower level, the atom emits a photon of light with the same energy that the atom originally absorbed. The...

That’s the question Shor answered, in what remains “the major result in our field,” according to Edward Farhi, the director of MIT’s Center for Theoretical Physics, who also researches quantum computation. When a particle in superposition randomly assumes a single state, it does so in acc...
But in physics, we don’t decide matters based on arguments, but rather on experiments. If we can write down the laws that govern reality — and we have a pretty good idea of how to do that for quantum systems — then we can derive the expected, probabilistic behavior of the system. ...
Quantum mechanics (QM; also known as quantum physics, or quantum theory) is a fundamental branch of physics which deals with physical phenomena at nanoscopic scales, where the action is on the order of the Planck constant. The name derives from the observation that some physical quantities can ...
to favour placing QMs in ground stations. However, during the 6 years since the proposal, atomic physics experiments have made a leap into space, mainly for atom interferometry and optical clock applications. Thus the feasibility and performance of QR architectures that operate in space should be ...
A great childhood memory that I have comes from first playing “The Incredible Machine” on PC in the early 90’s. For those not in the know, this is a physics-based puzzle game about building Rube Goldberg style contraptions to achieve given tasks. What made this game a standout for me...
A word of caution – your score on each scale was interpreted relative to a large (2448) sample of other people who have done the test: ‘relatively low’ means your score was in the bottom 30%, ‘relatively high’ in the top 30%, and ‘about average’ somewhere in the middle. Howev...
I believe this applies to photons and particles in general. The equations for physics always seem to allow collisions to be reversable and there are no laws that would not allow any set of particle interactions to be reversible. However, it is my opinion that photons are not reversible for ...
Introduction The large Hilbert space of a quantum system and the quantum superposition principle offer the potential advantages of quantum physics in many applications and laid the foundation of quantum information science1. Recently, supported by the established quantum state engineering and control techni...
