Welcome to the next generation of computing
This is where you find technology as pioneering as your own work. The quantum hardware at the core of our systems is cooled by a dilution refrigerator. Take a look inside and click on the numbered points to see how it all comes together.
The Machine
1Dilution Refrigerator
When the computer is operational, five casings (like the white one shown at the top of the image) envelop the machine. These cans nest inside each other and act as thermal and radiation shields, keeping everything super cold and vacuum-sealed.
The Machine
2Signal Chain
These cables deliver and condition microwave signals to and from the chip to drive qubit operations and return the measured results.
The Machine
3Temperature Stages
These gold-plated copper plates separate cooling zones. At the bottom, they plunge to one-hundredth of a Kelvin—hundreds of times as cold as outer space.
The Machine
4Mixing Chamber
At the lowest, coldest plate sits the most critical hardware, including amplifiers, additional cables, filters, and the mounts that hold the quantum processing unit.
The Machine
5QPU
The QPU (quantum processing unit) is a superconducting quantum integrated circuit that powers the quantum computer, inside a metal package that thermalizes it and shields it from the environment.

Localized thermometry via Dayem bridges integrated on superconducting qubit chips
Here we demonstrate a complementary on-chip thermometry method based on superconducting Dayem bridges that are integrated on the same chip as transmon qubits. By extracting the critical current of the Dayem bridge from I-V measurements, we obtain a local, quantitative measure of the chip temperature without the need for microwave calibration or qubit-specific control sequences.

Demonstrating real-time and low-latency quantum error correction with superconducting qubits
Quantum error correction will be essential for quantum computers to realize their full potential. As quantum computers advance towards demonstrating a universal fault-tolerant logical gate set, implementing scalable and low-latency real-time decoding will be crucial to avoid an exponential slowdown and maintain a fast logical clock rate. Here, we demonstrate low-latency feedback with a scalable FPGA decoder integrated into the control system of a superconducting quantum processor.

Unlocking a fast adiabatic CZ gate and exact residual ZZ cancellation between fixed-frequency transmons using a floating tunable coupler
In this work, we demonstrate that a symmetric floating tunable coupler provides a natural platform for fast, high-fidelity adiabatic controlled-Z (CZ) gates. Its favorable energy-level structure eliminates the conventional trade-off between rapid conditional-phase accumulation and adiabatic evolution while preserving exact cancellation of residual ZZ interaction at idling.

Qubit-efficient quantum combinatorial optimization solver
Quantum optimization solvers typically rely on one-variable-to-one-qubit mapping. However, the low qubit count on current quantum computers is a major obstacle in competing against classical methods. Here, we develop a qubit-efficient algorithm that overcomes this limitation by mapping a candidate bit string solution to an entangled wave function of fewer qubits. We propose a variational quantum circuit generalizing the quantum approximate optimization ansatz (QAOA).
