QuantWare Releases an Off-the-Shelf 25 Qubit Superconducting Processor Chip

For those who want to build their own superconducting quantum computer, Dutch startup Quantware is now offering an off-the-shelf 25 qubits superconducting processor chip with a 30 day delivery time after receipt of order. The product is called Contralto and key specifications include the following:

1. Customizable topology and Hamiltonian parameters

2. Customizable features include: Purcell filters, AirBridges and QuantWare's proprietary TSV configuration

3. Fully controllable qubits with dedicated flux bias and drive lines

4. 10 - 60 μs T1 (subject to stack quality)

5. 99.9% single-qubit gate fidelities

6. Delivered as die or fully packaged

7. Magnetic shielding available as option

8. 30 day lead time

Contralto is a follow-on to a previous 5 qubit product called Soprano which the company indicates has been installed in labs on four different continents. To be sure, a superconducting chip is not the same as a full quantum computer. Users will need to add a classical computer, control electronics, dilution refrigerator, cabling systems, and mechanical packaging. But all of those pieces are available from other vendors so a user can construct their own quantum machine from all the components.
