Two PhD projects are available in optical clocks and mmWave photonics: Two PhD Scholarships in Sydney: Ultra-narrow linewidth lasers for optical atomic clocks and mmWave frequency combs Submitted by richmildren on Thu, 15/02/2024 – 22:48. […]
In an experiment akin to stop-motion photography, scientists have isolated the energetic movement of an electron while “freezing” the motion of the much larger atom it orbits in a sample of liquid water. Click to […]
Creating a quantum computer powerful enough to tackle problems we cannot solve with current computers remains a big challenge for quantum physicists. A well-functioning quantum simulator—a specific type of quantum computer—could lead to new discoveries […]
If gravitational condensate stars (or gravastars) actually existed, they would look similar to black holes to a distant observer. Two theoretical physicists have now found a new solution to Albert Einstein’s theory of general relativity, […]
Making quantum systems more scalable is one of the key requirements for the further development of quantum computers because the advantages they offer become increasingly evident as the systems are scaled up. Researchers at TU […]
In Disney’s 1959 film Donald in Mathmagic Land, Donald Duck, inspired by the narrator’s descriptions of the geometry of billiards, energetically strikes the cue ball, sending it ricocheting around the table before it finally hits […]
An international research team from Innsbruck and Geneva has developed a new thermometry method to measure temperatures for low-dimensional quantum gases. With this method it was found that compressing a gas may lead to cooling. […]
Quantum 8, 1257 (2024). https://doi.org/10.22331/q-2024-02-15-1257 We propose a novel deterministic method for preparing arbitrary quantum states. When our protocol is compiled into CNOT and arbitrary single-qubit gates, it prepares an $N$-dimensional state in depth $O(log(N))$ […]
We often talk about evolution in terms of competition, as the survival of the fittest. But if it is, then where did the widespread (and widely admired) impulse to help others even at great cost […]
