Netherlands startup QuantWare is launching a 64-Kbit processor based on superconducting circuits, Tech.eu reports.
QuantWare’s quantum processor, called Tenor, has been chosen to run Israel’s first fully functioning quantum computer. It is claimed to offer 10 times lower cost than competing superconductor-powered quantum computers.
Such superconductors are used to create qubit atoms charged in such a way that they perform quantum entanglement, which in theory allows many more calculations to be performed synchronously.
“Because qubits are fully controllable, these processors are well suited for powerful error correction circuits. Such a design requires more connections per qubit than the commonly used fixed-frequency qubits, and as such were impossible to scale from 64 qubits with conventional planar devices.”
states the company.
QuantWare argues that earlier-generation superconducting devices require planar connections between qubits and the outside world, typically routed to the edges of the chip.
With its patented three-dimensional technology, it proposes to route qubits vertically to hypothetically stack thousands of entangled superconducting qubits, increasing the number of connections that its architecture can house.
The main advantage over some of the alternatives is that experts know more about controlling superconducting qubits and correcting errors-they’ve been around for decades. But the temperature requirement is another obstacle to scaling.
