   "Scientists from MIT’s Computer Science and Artificial Intelligence
   (CSAIL) have created Twist – a programming language
   for [2]quantum computing. The language uses a concept called purity,
   which enforces the absence of entanglement and results in intuitive
   programs, with fewer bugs. Twist can describe and verify which pieces
   of data are entangled in a quantum program, using a language a
   programmer can understand.

   "Programming [3]quantum computers requires awareness of entanglement.
   When two qubits are entangled, actions on one qubit can change the
   value of the other, even when they are physically separated. This
   potency is also a source of weakness. While programming, discarding one
   qubit without being mindful of its entanglement with another qubit can
   destroy the data stored in the other. This jeopardises the correctness
   of the program.

   “Our language [4]Twist allows a developer to write safer quantum
   programs by explicitly stating when a qubit must not be entangled with
   another,” said Charles Yuan, an MIT PhD student in electrical
   engineering and computer science and the lead author on a
   new [5]paper about Twist. “Because understanding quantum programs
   requires understanding entanglement, we hope that Twist paves the way
   to languages that make the unique challenges of quantum computing more
   accessible to programmers.”
