Quantum 6, 817 (2022). https://doi.org/10.22331/q-2022-09-22-817 We develop two general approaches to characterising the manipulation of quantum states by means of probabilistic protocols constrained by the limitations of some quantum resource theory. First, we give a […]
Quantum 6, 816 (2022). https://doi.org/10.22331/q-2022-09-22-816 Quantum many-body systems involving bosonic modes or gauge fields have infinite-dimensional local Hilbert spaces which must be truncated to perform simulations of real-time dynamics on classical or quantum computers. To […]
Quantum 6, 815 (2022). https://doi.org/10.22331/q-2022-09-22-815 We propose an extension to the Pauli stabiliser formalism that includes fractional $2pi/N$ rotations around the $Z$ axis for some integer $N$. The resulting generalised stabiliser formalism – denoted the […]
A few minutes into a 2018 talk at the University of Michigan, Ian Tobasco picked up a large piece of paper and crumpled it into a seemingly disordered ball of chaos. He held it up […]
An international team of physicists, with the participation of the University of Augsburg, has for the first time confirmed an important theoretical prediction in quantum physics. The calculations for this are so complex that they […]
Quantum 6, 814 (2022). https://doi.org/10.22331/q-2022-09-22-814 Quantum technologies are moving towards the development of novel hardware devices based on quantum bits (qubits). In parallel to the development of quantum devices, efficient simulation tools are needed in […]
Cooling materials to extremely low temperatures is important for basic physics research as well as for technological applications. By improving a special refrigerator and a low-temperature thermometer, scientists have now managed to cool an electric […]
Millions of quantum bits are required for quantum computers to prove useful in practical applications. But this is still a long way off. One problem is that the qubits have to be very close to […]
Computers that can make use of the “spooky” properties of quantum mechanics to solve problems faster than current technology may sound alluring, but first they must overcome a massive disadvantage. Scientists from Japan may have […]
After two years of getting to know each other in 2D, it has been exciting to meet and reconnect with colleagues in the quantum industry. This week’s Quantum.Tech conference in Twickenham, London presented an opportunity […]
