Iceberg Quantum today announced its launch, a $2 million pre-seed funding round, and a partnership with PsiQuantum. The company is developing fault-tolerant quantum computing architectures based on LDPC codes, with the goal of accelerating the path to useful quantum computing using significantly less hardware.

Nu Quantum releases a Quantum Error Correction (QEC) theory paper demonstrating how a modular quantum computing architecture of interconnected processors is compatible with high-rate and efficient quantum error correction codes, charting a path towards fault-tolerant distributed quantum computing.

Quantinuum’s System Model H2 enabled Microsoft’s qubit-virtualization system to generate the most reliable logical qubits ever recorded, a breakthrough with wide ranging implications for everyone in quantum computing, accelerating progress and challenging current assumptions about the timeline toward large scale reliable quantum computing.

Quantinuum just put a huge dent in the scaling problem with their latest result, using a clever approach to minimize the number of signals needed to control the qubits, in a way that doesn’t scale prohibitively with the number of qubits.
