    "abstract": "Security trade-offs have been established for one-way bit commitment in\nquant-ph/0106019. We study this trade-off in two superselection settings. We\nshow that for an `abelian\u0027 superselection rule (exemplified by particle\nconservation) the standard trade-off between sealing and binding properties\nstill holds. For the non-abelian case (exemplified by angular momentum\nconservation) the security trade-off can be more subtle, which we illustrate by\nshowing that if the bit-commitment is forced to be ancilla-free an\nasymptotically secure quantum bit commitment is possible.",
