Build a fault-tolerant QCCD quantum computer!

On this website, you can learn how to design a QCCD quantum computer, compile any quantum program to your QCCD quantum computer, and evaluate the performance!

Part of FTL: Accelerating Fault-Tolerant Quantum Logic, the NSF National Quantum Virtual Laboratory project, led by UCLA, that is designing a fault-tolerant trapped-ion computer with 60 logical qubits.
