Your press review from Quantaneo
A team led by Professor Michelle Simmons, has developed the fastest ever two-qubit gate between atoms suspended in silicon. The extremely small logic gate completed an operation in 0.8 nanoseconds – roughly 200 times faster than other spin-based two-qubit gates. Similar to how a classical computer works based on transistors in on/off states (bits), this quantum computer represents the spin orientation of electrons as binary information (qubits).
Quantum computers will pose a serious threat to the cryptographic systems which underpin much of our current computer security. Experts at the University of Waterloo have calculated that there is a 1 in 7 chance of these crypto primitives being affected by quantum attacks in 2026, and a 1 in 2 chance by 2031.
Another application in national security, is hidden object detection: by taking advantage of the unique precision of quantum technology to measure the moment a photon hits a sensor, for example, you can develop detection systems to visualize and track objects that are outside the visual field.
Quantum entanglement could also be used to create and visualize the double quantum of an object. Light is passed through a crystal with the right nonlinear optical properties which will split some of the photons into two ‘entangled’ daughter photons. One of the daughter photons is directed towards the object to be imaged, and the other is directed towards the sensor doing the imaging.
The entangled photons have quantum states which are intrinsically linked and measurable, allowing the properties of the daughter that hits the object to be deducted from the other daughter that hits the sensor, ultimately allowing an image to be constructed.
