Quantum computing that scales like semiconductors.

Relaxation times of up to a second and dephasing times exceeding tens of milliseconds exceed the values for superconducting qubits by three and one order of magnitude, respectively.

Unlike for superconducting qubits, coherence is robust up to operating temperatures of 1 K and insensitive to thermal radiation, background radioactivity and cosmic rays. ARQUE's shuttling-based technology allows connecting distant qubits, which improves algorithmic performance compared to locally coupled superconducting qubits. The large separation of uncoupled qubits, strong screening, low operating frequency and the absence of resonators avoid crosstalk-problems common for other platforms. The clock frequency is a factor 1000 better than for trapped ion qubits.

Most applications of quantum computing need to implement quantum error correction to mitigate unavoidable errors. With our approach, at least 1 Million qubits can be placed on a 1 cm x 1 cm silicon chip, thus reaching the qubit number needed for error correction. This will enable quantum advantage for industry relevant problems well beyond current NISQ applications.

Superconducting qubits in contrast have sizes on the mm-scale, and a proposal for scaling ion traps estimates 10 m² for 10⁶ qubits.

Our technology is based on commercial CMOS production lines, thus leveraging the only available technology to economically realize billions of functional units in a single conventional processor.

Due to the robust coherence, higher operating temperature and purely electrostatic control, our qubits are well-suited for using highly integrated cryo-electronic control systems. This allows to overcome the limitations of external control systems with macroscopic wiring and leads to excellent scaling perspectives.
