QDNC Issue #13

  • Scientists in US and Russia have managed to return three qubits to their state a fraction of a second earlier, demonstrating time reversal in a quantum computer. Qubits were set to a state of 0, after which order is lost and qubits grew in complexity in a pattern of 0s and 1s. Then, time was reserved by a program that allows the QC to go from chaos to order (complex to simple). Qubits, in this way, were sent back in time. Success rate was 85% with two qubits, and falls with every qubit added, indicating that this time-reversal is negligible in the material world. However, time reversing has bearings on quantum computer programs – while we could not measure its state without destroying superposition and projecting a component with some probability, we have a method of time-reversing the QC to its initial state with this demonstration.
  • Zeus is the AirBnb for white collar transient workers, raking in 45 millon in revenue and raising $24 million in their latest round. Its managed ownership model means that Zeus takes over furnishing and upkeep while homeowners profit. It fits into the niche area between AirBnb’s short term stay and other larger, long-term apartment rentals.
