title : Quantum Network Information Theory

Generalize classical multi-user information theory to quantum networks:

• Quantum multiple access channels
• Quantum interference channels
• Entanglement routing capacity in large-scale quantum internet

Critical for the future quantum internet and distributed quantum computing.

Scope Alignment (Mandatory)

Tell the writer:

• The paper must focus on fundamental limits, not system implementation.
• Core contribution must be new theorems, capacity bounds, or converse proofs.
• Work must clearly extend classical network information theory into the quantum regime.
• Avoid engineering optimization unless supported by new theoretical proofs.

No simulation-only papers
No architecture-only discussion
No review/survey style

2? Mathematical Depth Requirements

Require:

• Formal problem definition using Hilbert spaces and CPTP maps
• Precise channel model (e.g., quantum MAC, broadcast channel, interference channel)
• Clearly stated Theorems, Lemmas, and Corollaries
• Complete proofs (no sketch-only arguments unless standard)
• Converse + Achievability results if proposing capacity regions
• Use of quantum entropy measures:
  • Von Neumann entropy
  • Coherent information
  • Holevo information

The paper should look like classical Shannon theory but quantum.

3? Expected Structure (TIT Standard)

Instruct them to follow this structure:

1. Introduction
   • Clear gap in existing quantum network literature
   • Why classical results do not directly extend
   • Summary of contributions
2. System Model
   • Mathematical channel definitions
   • Assumptions
3. Main Results
   • Theorem statements
   • Capacity region expressions
4. Proof Sections
   • Achievability proof
   • Converse proof
5. Special Cases / Extensions
   • Reduction to classical case
   • Entanglement-assisted version
6. Discussion (Short and Technical)
   • Implications for quantum internet

---

4? Novelty Requirement (Very Important)

Tell them:

The manuscript must contribute at least one of:

• New quantum network capacity region
• New outer bound tighter than existing literature
• New coding scheme (quantum superposition coding, etc.)
• Non-asymptotic bounds
• Strong converse theorem

Incremental extensions of known results will be rejected.

---

5? Literature Benchmarking

They must compare against major quantum information results and show how this work advances beyond:

• Multi-user classical information theory
• Known quantum Shannon theory results
• Existing quantum MAC/broadcast papers

Explicit comparison section required.

---

6? Writing Style Requirements

Tell them:

• No informal explanations dominating the paper
• No marketing language
• No buzzwords (AI, blockchain, etc.) unless mathematically formalized
• Clear notation table
• Consistent symbols throughout

---

7? Technical Quality Checks (Before Submission)

Ask the writer to verify:

All entropy identities are correct
All inequalities are justified (data processing, strong subadditivity, etc.)
No unproven assumptions
All proofs logically complete
All claims mathematically supported

---

8? Formatting Compliance

Follow IEEE TIT guidelines:

• Two-column IEEE format
• Proper theorem environments
• Correct reference style
• Page limit respected

---

9? What Reviewers Will Look For

Tell the writer the reviewers will ask:

• Is this fundamentally new?
• Is the math correct and non-trivial?
• Does this generalize classical theory meaningfully?
• Is the capacity region tight?

If the answer to any is weak rejection likely.

Golden Rule for Acceptance

For IEEE Transactions on Information Theory, the paper must answer:

“What new fundamental limit of quantum information transmission does this work establish?”

If it cannot answer that clearly it will not be accepted.
