- [Arctic Instruments Introduces AI-TWPA-C-M ](https://arcticinst.io/arctic-instruments-introduces-ai-twpa-c-m/): Arctic Instruments announces the release of AI-TWPA-C-M, a compact, pre-assembled travelling wave parametric amplifier (TWPA) module designed for cryogenic microwave readout applications. 
- [AI-TWPA-C: now equipped with an on-chip pump coupler](https://arcticinst.io/ai-twpa-c-equipped-with-an-on-chip-pump-coupler/): We announce the launch of a revised AI-TWPA-C equipped with an on-chip pump coupler that provides advances on both fronts. The path towards quantum utility is paved with hard-earned hardware and software advances. Among the hardware challenges superconducting quantum computers face when scaling up, one is related to qubit readout: how does one deal with the increasing number of qubit readout signals in the limited volume and mass budget available in dilution refrigerators? To address the challenge, one can frequency multiplex more qubits per readout line and/or decrease the volume taken up by each readout line.
- [Record-breaking superconducting qubit coherence](https://arcticinst.io/press-release-number-1/): In a just published article in Nature Communications, Tuokkola et al. characterize a transmon qubit with energy relaxation and echo dephasing times surpassing those in the existing literature, utilizing a traveling-wave parametric amplifier (TWPA) from VTT. This TWPA is from an early prototype run, based on which AI-TWPA-C was created.

- [Product](https://arcticinst.io/ai-twpa-c/): Our amplifiers, such as AI-TWPA-C, are placed close to the QPU to increase the amplitude of these extremely weak signals encoding the qubit states. The uncertainty principle mandates that any amplifier like this must add a certain minimum quantity of noise to the amplified signal. In our factory testing, we verify that each individual amplifier we ship gets close to this so called standard quantum limit (SQL).
