As noted by Lance, the new journal ACM Transactions on Computation Theory is now accepting papers. Note for quantum computing theorists:
ACM Transactions on Computation Theory will cover theoretical computer science complementing the scope of the ACM Transactions on Algorithms and the ACM Transactions on Computational Logic including, but not limited to, computational complexity, foundations of cryptography, randomness in computing, coding theory, models of computation including parallel, distributed and quantum and other emerging models, computational learning theory, theoretical computer science aspects of areas such as databases, information retrieval, economic models and networks.
So next time you write a paper which involves QMA, the Hidden Subgroup, etc. etc. make sure to give ToCT a look!
This is quite useful! Thanks for the post.
