Yesterday, we looked at the physical gate-based qubit leaderboard that I have been tracking for the last few months [1]. Today, as promised we are pivoting to look into the largest logical qubit based systems. This updated view reframes what it means to be the “largest” quantum computer. I’m still more interested in who will run Shor’s algorithm and dem…
