A particle can carry more than one bit of information
<|reference_start|>A particle can carry more than one bit of information: It is believed that a particle cannot carry more than one bit of information. It is pointed out that particle or single-particle quantum state can carry more than one bit of information. It implies that minimum energy cost of transmitting a bit will be less than the accepted limit KTlog2.<|reference_end|>
