In theory, quantum physics can bypass the hard mathematical problems at the root of modern encryption. A new proof shows how.

Lauda and his colleagues solve some of the problems with topological qubits by using a class of theoretical particles they call neglectons, named for how they were derived from overlooked theoretical ...

Japanese scientists develop scalable quantum LDPC error correction codes approaching the theoretical hashing bound.

Recently, Professor Zong Chuanming from the Center for Applied Mathematics at Tianjin University published a paper titled ...

Chicago has quickly emerged as a hub for quantum computing, with the state of Illinois and technology companies pouring ...

Imagine the tap of a card that bought you a cup of coffee this morning also let a hacker halfway across the world access your bank account and buy themselves whatever they liked. Now imagine it wasn’t ...

Experimental setup to couple MWs to N- 𝑉⁢s using grape dimers. A stripped optical fiber with N- 𝑉 spins, cantilevered from a rod, lies between two grapes. The grapes were positioned on a platform ...

The Fourier transform is a mathematical operation essential to virtually all fields of physics and engineering. Although there already exists an algorithm that computes the Fourier transform in ...

Encryption—the process of sending a scrambled message that only the intended recipient’s device can decode—allows private and public sectors alike to safeguard information. Traditional encryption uses ...

The renowned physicist Richard Feynman is reputed to have once said that “physics is to math what sex is to masturbation”. Exactly what comparison he was making, he didn’t clarify – but if the orgasm ...

The original version of this story appeared in Quanta Magazine. Hard problems are usually not a welcome sight. But cryptographers love them. That’s because certain hard math problems underpin the ...
