Demonstration of teleportation-based error correction in the IBM quantum
  computer
Quantum error correcting codes (QECC) are the key ingredients both for
fault-tolerant quantum computation and quantum communication.
Teleportation-based error correction (TEC) helps in detecting and correcting
operational and erasure errors by performing X and Z measurements during
teleportation. Here we demonstrate the TEC protocol for the detection and
correction of a single bit-flip error by proposing a new quantum circuit. A
single phase-flip error can also be detected and corrected using the above
protocol. For the first time, we illustrate detection and correction of erasure
error in the superconducting qubit-based IBM's 14-qubit quantum computer.
