Abstra ct : EPR state as the most basic quantum entangled state plays an important role in quantum teleportation. In this work, the
universal single-qubit quantum teleportation adapted to any type of EPR channel is studied and gen eralized to universal N-qubit quantum
teleportation. In the single-bit quantum teleportation mode with four kinds of EPR states as quantum channels respectively, design
single-bit universal circuits by analyzing the relationship between the EPR and the quantum gate, then design a two-bit standard quantum
teleportation circuit and use Mathematica to verify the correctn ess of the circuit, and then g en er al ize it to an N-bit qu antum teleportation
circuit, the next step, the single-qubit universal circuit and the N-qubit quantum teleportation circuit are implemented for fusion, finally
any N-bit quantum teleportation universal circuit is designed. The universal circuits for N-particle quantum bits perform unitary
transformation with parameters by the recipient of the information, where the parameters are determined by the type of EPR prepared ,
which solves the problem of information tr ansmission f ailure due to an error in the EPR preparation center.
Key words: quantu m teleportation; universal circuit; EPR state; entangled state; quantum channel
