Pine System - 20 qubit control AQT Alpine Quantum Technologies

Access 20 fully-connected qubits using a 19-inch rack

We offer a fully functioning 20-qubit quantum computer, ready for the integration into existing IT infrastructure and cloud accessibility, inside a standardised 19-inch rack.

The individual qubit control in the AQT PINE trap is demonstrated by a measurement showing the crosstalk between the qubits, here exemplified for a 20 qubit register. A single qubit out of the chain is addressed and excited individually and coherently by a laser beam. The influence of this operation on the surrounding qubits is monitored and quantified. This procedure is repeated for all qubits of the register and the cross-talk ratios are documented in a matrix table.

Interesting algorithms require more qubits.
We offer 20 qubits ‘out of the rack’.

Connectivity and performance limit end-users from implementing quantum algorithms. Our solutions have demonstrated fault-tolerant performance levels.

20-QUBIT ALGORITHMS – AND NO THOUGHT SPEND ON CONNECTIVITY
20-qubit algorithms – and no thought spend on connectivity

Our fully-connected quantum register allows you to connect any qubit to any other qubit without a computational overhead that generally reduces the performance.

CROSS-TALK BETWEEN QUBITS IS UNDESIRED – AND AT A FAULT-TOLERANT LEVEL IN OUR SOLUTION
Cross-talk between qubits is undesired – and at a fault-tolerant level in our solution.

Reduced cross-talk allows end-users to implement algorithms without considerations to know or implement hardware-specific error mitigation techniques.

Scalability via quantum error correction requires error rates smaller than 1%. Here we demonstrate cross-talk error rates at the 1e-5 level.

The low error rates provide the confidence that AQT offers long-term solutions that enable error correction routines out of the box, supporting more qubits and even lower error rates.

Our PINE system is the first quantum computer that fits inside two standardized 19-inch racks. Building on top of the ion-trap quantum computing platform pioneered in Innsbruck, Austria, tens of ion-qubits can be worked with. Here we provide a teaser on the characterisation of operating a stand and 20 qubit quantum register. The characterisation shows out-of-the box performance compatible with fault-tolerant quantum computing.

In our ion-trap quantum computer, we move a laser beam onto the position of an ion or multiple ions. Discrete laser pulses onto the ions change the encoded quantum information. Ideally the laser light would hit only the targeted ion(s) and nothing else. Here we characterize the undesired coupling of the laser lightfield via the coupling strength of non-targeted ions relative to the addressed ion-qubit in a 20-qubit register. Typical numbers are usually in the range of 1-3%. Here, we show average coupling to next-neighbor qubits of about 0.6%. In terms of error rates, this is in the 1e-5 range and compatible with fault-tolerant requirements. Adding additional error mitigation routines allow to suppress this value to the 1e-7 level. Such levels are better than what is currently considered to be necessary for fault-tolerant quantum computing.

These low values show that end-users can execute quantum algorithms on our device without considering error mitigation routines. Seeing that we support a wide range of quantum software development kits such as Qiskit, Cirq, PennyLane, Pytket, … existing code can be readily tested on our devices and without requiring detailed knowledge of the underlying hardware.

To date, our solutions have been used to demonstrate a universal gate-set for logical qubits.
