  Superconducting parametric amplifiers are crucial components in microwave
quantum circuits for enabling quantum-limited signal readout. The
best-performing such amplifiers are often based on Josephson junctions, which
however are sensitive to magnetic fields. Therefore, they require magnetic
shields and are not easily integratable with other quantum systems that
operates within magnetic fields, such as spin ensemble quantum memories. To
tackle this challenge, we have developed a kinetic inductance-based parametric
amplifier featuring a NbN nanobridge instead of Josephson Junctions, which
provides the desired nonlinearity for a strong parametric gain up to 42 dB. The
added noise of this nanobridge kinetic-inductance parametric amplifier (hereby
referred as NKPA) is calibrated and found to be $0.59\pm 0.03$ quanta for
phase-preserving amplification, approaching the quantum limit of 0.5 quanta.
Most importantly, we show that such excellent noise performance is preserved in
an in-plane magnetic field up to 427 mT, the maximum field available in our
experiment. This magnetic field-resilient parametric amplifier presents an
opportunity towards addressing single electron-spin resonance and more
efficient search for Axions as well as Majorana Fermions.
