Planckian is developing the core technology to power utility-scale quantum computers. By design, our chip architecture decouples control lines from qubit count, removing a key bottleneck in scaling. It combines the proven reliability of superconducting circuits with a breakthrough approach to qubit control, paving the way for quantum computers capable of solving the world's most challenging problems.
What You'll be doing
