QSea I & QSea II · Digital twins
Fully simulated digital twins
Key Facts
– Complete simulation of the QSea I & QSea II hardware
– Freely adjustable noise sources and parameters
– Up to 20 simulated qubits
– All-to-all connectivity
– Switchable extra functions
Like the real thing, only better
Sometimes it has to be a simulacrum: With this digital twin of the QSea I, we not only provide a realistic simulation of the real hardware, but also make it possible to fine-tune its parameters. This allows us to develop tricky quantum algorithms that utilise the real properties of the system, such as its noise. And agile algorithms can be tested under controlled conditions before they are implemented on the real system.

REDAC
Fully digitally configurable analogue computer (yes)
Key Facts
– solves ODEs, PDEs, signal primitives, neural-network inference, and emulates gate-based quantum circuits
– two hardware time-scale factors: k₀ = 100 and k₀ = 10,000
– 2,688 summing lanes and > 1,000 sample-&-hold stages
– 200 selectable functions
– modular and virtualizable
– analog bandwidth 100 kHz – 1 MHz
– full software stack with the typed analang language and the redacc compiler
– and sooo much more
The analogue future of compute
The REDAC is the analog-computing member of the DLR QCI portfolio: a reconfigurable analog–digital hybrid computer that solves differential equations directly in continuous-time physics, running at room temperature in the 1–100 W range. It solves ODEs, PDEs, signal primitives and neural-network inference, and — developed with the DLR Institute of Quantum Technologies — it emulates gate-based quantum circuits by an exact classical mapping to coupled harmonic oscillators (Briggs & Eisfeld), importing circuits from Qiskit and reproducing a 3-qubit QFT at 0.9943 fidelity. It complements the initiative’s qubit platforms, is deployed at DLR today, and ships with a full compiler and cloud software stack – and you can access it here on Connect.

XQ1i
Room temperatur NV center demonstrator

Robust quantum computing
With a system like this you can use a handfull of real qubits for (some) real world problems like using noise for the simulation of molecules in their environment or an H2 molecule on just one qubit. This won’t solve big scientific questions or enable new quantum algorithms, but it will get you ahead in understanding the behaviour of real quantum hardware.
