Summary:
A team of researchers led by John Teufel and José Aumentado at NIST has made significant progress in quantum mechanics by demonstrating the entanglement of two macroscopic mechanical resonators. These resonators have masses on the order of tens of picograms, which is equivalent to 10^12 atoms. This groundbreaking experiment has tested the physical size limits at which quantum mechanics transitions into classical physics.
The techniques developed in this research could have practical applications in continuous-variable quantum computing. In these quantum computing schemes, fast entangling operations are as important as logic gates. The successful demonstration of entanglement in macroscopic mechanical systems could pave the way for more efficient and scalable quantum computing technologies in the future.
