Title: NIST Quantum Squeezing Technique Boosts Dark Matter Search
NIST researchers have developed a quantum squeezing technique that significantly improves the sensitivity of dark matter detectors. The technique, used in the Yale University axion search project HAYSTAC, allows scientists to scan a broader frequency range for the hypothetical axion particles that may constitute dark matter.
The NIST amplifiers prepare an electromagnetic field in a squeezed state, reducing noise interference in the measurements. This allows HAYSTAC to detect even weaker signals from potential axion interactions. The collaboration between NIST and HAYSTAC has doubled the search rate for specific mass ranges of axions, bringing scientists one step closer to detecting this mysterious form of matter.
The implementation of quantum squeezing in dark matter searches represents a significant advancement in the field, potentially leading to the discovery of axions and shedding light on the nature of dark matter.
