QuLIPA
Quantum Limited Inductance Parametric Amplifier
Breaking Through the Noise Barrier
Classical amplification techniques struggle to amplify small signals without introducing significant noise, compromising output signal fidelity.
Current quantum methods, such as the Josephson Parametric Amplifier (JPA) and Josephson Traveling Wave Parametric Amplifier (JTWPA), are designed to introduce the least amount of added noise allowed by quantum mechanics. However, even these technologies have significant disadvantages. They are expensive, difficult to manufacture, and require dilution refrigeration systems to operate at extremely low temperatures, all while having poor power handling capabilities.
Our Amplifier overcomes these limitations. It operates at temperatures up to 4.5 degrees Kelvin, handles up to 1 Tesla magnetic field strengths, and has 3 orders of magnitude improvement in power handling, all while providing equal quantum noise performance to its JPA counterpart.
This innovative technology not only offers more powerful amplification but also does so at a fraction of the cost, making it a more accessible and commercially viable solution.
We are currently in the prototyping and deployment stage, seeking investors to bring this groundbreaking technology to market.
Our Solution
Operating Temperature
Due to the novel superconducting material we use to build our amplifiers, we can operate them at temperatures much higher that what is currently possible. A JPA must operate at a max temperature of 1K but usually become unstable and easily perturbed and so must operate at even lower temperatures. Our Amplifier operates at 4.5K while keeping high gain and bandwidth performance. This means that our device can be operated with smaller and cheaper cryostats that don’t require expensive materials and constant monitoring.
dB Compression
A standard measure of performance for any amplifier is it’s 1-dB compression power. This is the amount of input power required to saturate an amplifier and lower it’s gain by 1dB. Typical JPA technologies have 1-dB compression power on average of -105 dBm at 20dB gain, while our devices have a 1-dB compression of -73 dBm at 21dB of gain. This means that our amplifiers can handle 1500x more powerful input signals then the next leading technology (JPA).
Noise Introduction
Quantum mechanics necessitates that any amplifier must add some amount of energy to an input signal. We call this added energy noise, as it is an energy that can hinder our ability to measure the desired amplified signal. So having an amplifier that introduces small amounts of noise is not only desired but also necessary in some applications. When we compare our amplifier to classical versions we can see an improvement in the noise of over 40x, which allows for the amplification of sensitive signals reliably.
