The Logical Qubit Evolution
Transitioning to FTQC requires evolving from a physical qubit architecture to a logical qubit paradigm on the same neutral-atom hardware platform.
Physical qubits
Raw quantum systems are highly sensitive to environmental noise, which can introduce decoherence and calculation errors.
Logical qubits
By entangling an array of physical qubits, systems can encode a single, highly stable logical qubit capable of executing complex fault-tolerant gates.
Ancillary qubits
These physical qubits are measured to detect syndrome errors dynamically, allowing the system to correct faults without destroying the quantum state of the logical qubit.
The Logical Qubit Solution
Scaling Logical Architecture
Generating high-fidelity logical qubits requires significant physical qubit overhead. Pasqal’s scalable neutral-atom architecture aims to yield 200+ logical qubits by 2029, targeting this fundamental trade-off.
