Quantum random access codes[QRACs]are important communication tasks that are usually implemented in prepare-and-measure scenarios.The receiver tries to retrieve one arbitrarily chosen bit of the original bit-string from the code qubit sent by the sender.In this Letter,we analyze in detail the sequential version of the 3 → 1 QRAC with two receivers.The average successful probability for the strategy of unsharp measurement is derived.The prepare-and-measure strategy within pro-jective measurement is also discussed.It is found that sequential 3 → 1 QRAC with weak measurement cannot be always superior to the one with projective measurement,as the 2 → 1 version can be.
