Pasqal QPUs Information
Pasqal specializes in neutral atom quantum computing, controlling Rydberg atoms with high-precision optical tweezers. Their technology allows for arbitrary 2D and 3D topology and operates in Analog mode, which is particularly well suited for large-scale quantum simulation and optimization problems involving up to a hundred qubits.
Key features
- Scalability: Pasqal's neutral atom technology allows for a high number of qubits in a single device, making it suitable for complex quantum algorithms.
- Reconfigurable topology: Atoms can be arranged in arbitrary 2D patterns, enabling flexible connectivity for various algorithms.
- Analog mode: Operates primarily as a quantum simulator (Hamiltonian evolution) rather than a gate-based computer, offering a different path to quantum advantage.
Use cases
The Pasqal QPUs are particularly well suited for:
- Quantum simulation: Simulating complex quantum systems, especially in chemistry and material science.
- Optimization problems: Solving combinatorial optimization problems in QUBO representation using variational algorithms like QAOA
Pasqal QPUs and emulators available at Scaleway
Scaleway provides access to Pasqal's "Orion Gamma" generation devices and their digital twins.
- **Fresnel (100 Qubits) QPU allows you to trap and control over 100 atoms. It exploits the Rydberg blockade mechanism to create entanglement between atoms.
- Locations: We provide access to two geographically distinct units:
QPU-FRESNEL-100PQ(Located in Massy, France)QPU-DISTRIQ-100PQ(Located in Sherbrooke, Canada)- Note: Both devices offer similar specifications.
| Platform name | QPU Model | Qubits & Topology | Speed Metrics | Pricing Model | | :--- | :--- | :--- | :--- | :--- | :--- | | QPU-FRESNEL-100PQ | Orion Beta | 100 atoms, 2D layout | shots: 0.25hz | 3.3€/shot (~0.83€/sec) | | QPU-DISTRIQ-100PQ | Orion Beta | 100 atoms, 2D layout | shots: 0.25hz | 3.3€/shot (~0.83€/sec) |
We provide access to high-performance emulation environment, leveraging DGX-class GPU clusters to create digital twins of Pasqal QPUs. This is a crucial tool for reliably prototyping and validating complex Analog pulse sequences before running them efficiently on the physical hardware.
| Platform name | Hardware & emulator | Qubits & topology | Speed metrics | Pricing model |
|---|---|---|---|---|
| EMU-FRESNEL-100PQ | A100 DGX cluster, Pulser | 100 atoms (tensor network), 2D layout | shots: 0.25hz | 11.2€/hour |
Pulser: The native SDK
To program neutral atoms, you don't typically use "Gates" (like CNOT or Hadamard) as the primary abstraction. Instead, you define Pulse Sequences using Pulser, Pasqal's open-source Python SDK.
Pulser allows you to:
- Define the register: Place your atoms at specific coordinates.
- Design the sequence: Define the laser pulses (amplitude, detuning, phase) applied to the atoms over time.
- Execute: Run the sequence locally or remotely.
On Scaleway QaaS, the integration is handled by the pulser-scaleway package, providing access to Pasqal QPUs and emulators.
