In the last months and years, I have stumbled upon many papers about quantum computing and some of the I have also read, some of them were just to Noble-prizy for me. Some were about the topology of quantum computers, some were about specific algorithms like Shor’s algorithm, some were about having fun with quantum computing, and some about physics (like Landauers Irreversibility and Heat Generation in the Computing Process or Benett’s Logical Reversibility of Computation).… Read more » “Realizing Quantum Computation”

“As explained by Science, to replicate the performance of Sycamore, the scientists first had to reconfigure the problem as a 3D mathematical array called a tensor network. This meant they could use the system’s GPUs to perform calculations in parallel.

The low level of accuracy of Sycamore’s computation gave the Chinese team additional room for manoeuvre.… Read more » “Google’s quantum supremacy debunked?”
