In new research, Google DeepMind has demonstrated that its AI can help accelerate the development of quantum computers — taking one step further in combining two of the most disruptive technologies. DeepMind worked together with UK-based Quantinuum to solve a key challenge in fault-tolerant quantum computers: reducing the number of T gates. T gates are essential in implementing a quantum circuit — a network of gates that manipulates qubits to generate algorithms. However, T gates are also the…

Acting on a tiny particle levitating in a magnetic trap, physicists have just measured the smallest gravitational pull ever recorded.The particle weighed just 0.43 grams. And the strength of the gravitational force at play was on the scale of attonewtons (10-18 newtons). That's small enough to be right on the verge of the quantum realm, teasing the possibility of finally figuring out how classical physics and quantum mechanics interact."For a century, scientists have tried and failed to understand how gravity and quantum…

The fractional quantum Hall effect has generally been seen under very high magnetic fields, but MIT physicists have now observed it in simple graphene. In a five-layer graphene/hexagonal boron nitride (hBN) moire superlattice, electrons (blue ball) interact with each other strongly and behave as if they are broken into fractional charges.

Within the next few decades, perhaps sooner, quantum computers will revolutionize the computing landscape by being able to carry out tasks thousands or even millions of times faster than today’s most powerful supercomputers. When that happens, a quantum computer of the future will easily be able to crack today’s end-to-end encryption technologies, leaving our messages in secure messaging apps like Apple’s iMessage, WhatsApp, and Signal vulnerable to malevolent nation states and bad actors.Even though sufficiently reliable…

Apple is introducing a new cryptographic protocol for iMessage that is designed to protect users from sophisticated attacks using quantum computers. The new encryption protocol could safeguard users from scenarios where encrypted data has been stored, only to be decrypted using a quantum computer at a later date. iMessage is the second messaging platform known to introduce support for quantum-security cryptography — Signal's PQXDH protocol was introduced last year — while adding another layer of security to protect users…
