World's heaviest Schrödinger's cat made in quantum crystal visible to the naked eye

Physicists have created the world's heaviest Schrödinger's cat, bringing the bizarre behavior of the quantum world to larger scales than ever before. The trick, performed by vibrating 100 million billion atoms inside a sand-grain-sized sapphire crystal, created the world's heaviest quantum superposition as the crystal simultaneously oscillated in two different...

Distortions in space-time could put Einstein's theory of relativity to the ultimate test

Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. According to new research published June 22 in the journal Nature Astronomy, the newly proposed method turns the edge of space and time into a vast cosmic lab to investigate if general relativity can account...

'The most magical equation in physics': How Paul Dirac accidentally revealed the strange world of antimatter

British theoretical physicist Paul Dirac was one of the most significant figures in the early days of quantum physics, who along with Erwin Schrödinger won the Nobel Prize for physics in 1933. But it was in 1927 that this quiet, but brilliant mind set to work looking for pretty mathematics,...

Quantum 'yin-yang' shows two photons being entangled in real-time

Scientists have used a first-of-its-kind technique to visualize two entangled light particles in real time — making them appear as a stunning quantum yin-yang symbol. The new method, called biphoton digital holography, uses an ultra high-precision camera and could be used to massively speed up future quantum measurements. The researchers...

World's largest gravitational wave observatory squeezes light beyond the 'quantum limit'

Scientists at the world's largest gravitational wave observatory have just squeezed light beyond a key quantum limit. The new technique, called frequency-dependent squeezing, will increase the number of tiny ripples in space-time detectable by the Laser Interferometer Gravitational-Wave Observatory (LIGO), boosting the number of neutron star and black hole collisions...
