The key to bigger quantum computers could be to build them like Legos

  • Visit any startup or university lab where quantum computers are being built, and it’s like entering a time warp to the 1960s—the heyday of mainframe computing, when small armies of technicians ministered to machines that could fill entire rooms.
  • The idea of bolting together smaller quantum building blocks to create bigger computers has been around for years, but it’s never quite caught on.
  • The smaller scale of each unit makes it easier to control the system and to apply error correction techniques.
