QuantWare, a provider of large-scale superconducting quantum processors, has launched Tenor, a new processor which features a massively scalable technology and enables quantum computers with 64 fully controllable qubits to be built commercially, says the company in a press release.

Superconducting qubits have led the quantum computing race for the last few decades, but have yet to scale to truly useful qubit counts because of scaling bottlenecks. Previous generation devices have been planar: the connections between the qubits and the outside world were routed to the edges of the chip. This limits the number of qubits to the numbers seen today.

3D technology

QuantWare has developed a 3D technology that routes the connections vertically, making it possible to scale superconducting quantum processors to thousands of qubits – opening the door to ‘quantum advantage’ where quantum computers will overtake the most powerful classical computer. Tenor marks a significant advance in commercial quantum computing because it is the first device commercially available that features this technology.

Twice the number of qubits

The quantum processor features 64 fully controllable qubits, which is a device with more than twice the number of qubits than the previously largest available quantum processor. Because the qubits are fully controllable, these processors are very suitable for powerful error-correction schemes. Such a design requires more connections per qubit than the often used fixed frequency qubits, and as such were impossible at a scale of 64 qubits with conventional planar devices. QuantWare brings the technology to the market at a 10x lower price point than competing solutions. 

Intel of quantum computing

QuantWare’s aim is to become the ‘Intel of quantum computing’ by providing easy-to-use, increasingly powerful and affordable quantum processors to organisations across the world. Last year, QuantWare was selected to deliver quantum processing units for Israel’s first fully functional quantum computer.
