U.S. Leads World in Quantum Computing Patent Filings with IBM Leading the Charge

Patenting activities in the quantum computing sector have rapidly increased in recent years, with the U.S. by far the preferred jurisdiction for applicants… One interesting finding from the Patinformatics report is that, although Northrop Grumman doesn’t have the largest portfolio in the field, it is well-situated to compete with the biggest players. “One of our main assertions is that, if there’s an organization interested in being competitive with IBM, they may want to contemplate a partnership or acquisition of Northrop Grumman,” Trippe said. Both Northrop and IBM have made significant investments into super-conducting loop qubit technologies and Northrop actually edges IBM in logic gate hardware.

The Fredkin gate takes us one step closer to quantum computers

In late March, reports came out that researchers from Griffith University and the University of Queensland demonstrated the Fredkin gate, also known as the controlled-SWAP gate. First conceived by American digital physicist Edward Fredkin, the Fredkin gate is designed to exchange values between qubits in a quantum computing system based on a value of a third qubit. The Fredkin gate is perhaps a foundational component to quantum computers, replacing circuits requiring five logic operations with circuitry which takes advantage of the quantum principle of entanglement.
