Running Shor's algorithm on a quantum device with error correction is a complex challenge that requires significant advancements in quantum control systems. The process of factorizing numbers, such as 21, illustrates the need for a large number of qubits and sophisticated error correction techniques. For instance, to factor 21, one would need 5 logical qubits, but implementing quantum error correction (QEC) with surface codes necessitates around 10^15 physical qubits due to error rates and the need for additional ancilla qubits. This highlights the technological hurdles in achieving fault-tolerant quantum computing. The OPX1000 quantum controller is designed to address these challenges by providing high-density control channels and real-time processing capabilities essential for managing thousands of qubits. Key requirements include maintaining phase stability to ensure low error rates, integrating classical computing for real-time decoding, and offering flexible programming to adapt to evolving quantum technologies. The collaboration between Quantum Machines and NVIDIA aims to enhance the performance of quantum systems by reducing latency in data processing, which is crucial for effective QEC. Overall, the development of advanced quantum control systems is vital for the practical application of quantum algorithms like Shor's.

The article suggests that only 5 logical qubits are needed to factor the product of two 3-bit primes, but how does one arrive at that number? Shor's algorithm requires performing a multiplication of two k-bit numbers, which would seem to require more than 2k-1 bits. So what do these 5 qubits correspond to exactly in Shor's algorithm?
Reading between the lines, we're many many many years away from being able to factor large primes.
