Z3948

Z3948 is the internal designation used by QuantumTech Inc. for its third‑generation quantum computing platform, introduced to the market in 2026. The system contains 128 transmon qubits arranged in a two‑dimensional lattice, with an average coherence time of 350 microseconds and a crosstalk error rate below 0.5 %. A cryogenic dilution refrigerator operating at 10 mK provides the necessary environment for the qubits, while a dedicated superconducting control electronics layer manages pulse generation and readout. The platform supports both gate‑based and variational quantum algorithms, with a native compiler that translates high‑level programming constructs into calibrated pulse sequences.

Z3948 is designed for a range of scientific and industrial applications, including material science simulations, cryptographic analysis, and optimization problems in logistics. Its modular architecture allows for expansion to 256 qubits through the addition of a second processing chip. The device has undergone preliminary characterization by the National Institute of Standards and Technology, which confirmed its performance metrics. Commercial deployment began in 2027, with several research institutions and corporations on board for pilot projects. As of early 2029, a continuous supply contract has been secured with the European Space Agency for use in space‑borne quantum sensing experiments. The Z3948 platform remains a flagship product within QuantumTech's portfolio, positioned as a bridge between current noisy intermediate‑scale quantum devices and forthcoming fault‑tolerant architectures.
