This Quantum Computer Is Sized for Server Rooms
Usually quantum computers are devices that can fill entire laboratories, but scientists in Austria have developed a compact 24-qubit quantum computer that can fit in two 19-inch server racks that performs at least on par with similar lab-scale setups.
For the First Time, Scientists Detect a Moving Photon Multiple Times Without Destroying It
Detecting photons typically requires absorbing them, however, researchers in Germany have detected a single photon twice without destroying it. Such findings could one day help scientists keep track of photons in quantum technology, leading to faster quantum computers and networks.
Google's Quantum Computer Exponentially Suppresses Errors
In a new study, Google scientists exponentially suppress error rates of their 54-qubit quantum computer "Sycamore" by scaling up a type of stabilizer code known as a repetition code. Such error suppression proved stable over 50 rounds of error correction.
