What is QuantWare's First 64 qubit processor?

Is this how the superconducting qubit approach scales?

Welcome Back,

QuantWare announced their new flagship quantum processor Tenor-64 on February 23rd, 2023. They claim Tenor is the first 64 qubit processor that features our 3D scaling technology that will enable superconducting qubits to massively scale.

Tenor-64’s technology solves the scaling bottlenecks for superconducting processors qubits by taking the connections out of the horizontal plane and into a vertical architecture.

According to their tema, it represents a big step forwards on the road to quantum advantage, and unlocks large-scale open-architecture quantum computers for the first time.

QuantWare based in the Netherlands, have come a long ways in just one year.

Tenor is Shining

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.

1. 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.

2. 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.

3. QuantWare has developed a patented 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.

4. Tenor marks a significant advance in commercial quantum computing because it is the first device commercially available that features this technology.

Some analysts were a bit skeptical reading the marketing PR.

Is this Startup the “Intel of Quantum” in the Making?

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 unlocks, according to the PR, these powerful devices for the quantum community by bringing its technology to the market at a 10x lower price point than competing solutions.

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.
